Fix task list checkbox toggle to work with YAML front matter (#25184)
Fixes #25160.

`data-source-position` of checkboxes in a task list was incorrect
whenever there was YAML front matter. This would result in issue content
or PR descriptions getting corrupted with random `x` or space characters
when a user checked or unchecked a task.

Fix math and mermaid rendering bugs (#24049)
1. Fix multiple error display for math and mermaid:


![err](https://user-images.githubusercontent.com/115237/231126411-8a21a777-cd53-4b7e-ac67-5332623106e8.gif)

2. Fix height calculation of certain mermaid diagrams by reading the
iframe inner height from it's document instead of parsing it from SVG:

Before:

After:

3. Refactor error handling to a common function
4. Rename to `renderAsciicast` for consistency
5. Improve mermaid loading sequence

Note: I did try `securityLevel: 'sandbox'` to make mermaid output a
iframe directly, but that showed a bug in mermaid where the iframe style
height was set incorrectly. Opened
https://github.com/mermaid-js/mermaid/issues/4289 for this.

Move helpers to be prefixed with `gt-` (#22879)
As discussed in #22847 the helpers in helpers.less need to have a
separate prefix as they are causing conflicts with fomantic styles

This will allow us to have the `.gt-hidden { display:none !important; }`
style that is needed to for the reverted PR.

Of note in doing this I have noticed that there was already a conflict
with at least one chroma style which this PR now avoids.

I've also added in the `gt-hidden` style that matches the tailwind one
and switched the code that needed it to use that.

Support asciicast files as new markup (#22448)
Support [asciicast
files](https://github.com/asciinema/asciinema/blob/develop/doc/asciicast-v2.md)
as a new markup via
[asciinema-player](https://github.com/asciinema/asciinema-player). For
more on asciinema, see the [introduction](https://asciinema.org/).

So users can use asciinema recorder to generate an asciicast file (or
you can download a sample file from
https://asciinema.org/a/335480.cast?dl=1), then upload it to Gitea and
play it on Gitea.

Known issue:

Don't support the [v1 version asciicast
files](https://github.com/asciinema/asciinema/blob/develop/doc/asciicast-v1.md),
it's a poorly designed version, it does not specify the file extension
and uses `*.json` usually, so it's impossible to recognize the files.

Fix environments for KaTeX and error reporting (#22453)
In #22447 it was noticed that display environments were not working
correctly. This was due to the setting displayMode not being set.

Further it was noticed that the error was not being displayed correctly.

This PR fixes both of these issues by forcibly setting the displayMode
setting and corrects an error in displayError.

Fix #22447

Add Mermaid copy button, avoid unnecessary tooltip hide (#22225)
- Add Copy button to mermaid diagrams which copies their source.
- Set tippy to not hide on click and avoid tooltip re-creation for
temporary tooltips. This avoids hide and show when copying repo url.
Popovers still hide the tooltip as usual.

Fix scroll over mermaid frame (#21925)
When starting a scroll while the mouse is over a mermaid diagram, the
scroll sometimes propagates to the iframe, preventing the parent page
from scrolling. Fix this by disabling scroll inside the iframe. This is
not a problem because those frames are never meant to scroll. Bug seems
to affect Firefox only.


![scroll](https://user-images.githubusercontent.com/115237/203847578-6831e3c8-9df4-4577-8501-822fb9ea1278.gif)

Fix opaque background on mermaid diagrams (#21642)
Browsers introduce a opaque background on iframes if the iframe
element's color-scheme does not match the document's color scheme which
in case of a dark theme results in a mismatch and the browser adds a
white background. Avoid this by specifying the same color scheme outside
and inside the iframe.

See https://fvsch.com/transparent-iframes for more info.

My initial attempt was to make the iframe document the same color-scheme
as the parent page (light or dark) but with that, there was a ugly
background flash on load in Chrome because Chrome apparently always
loads iframe in light scheme initially. Firefox still shows a background
flash on load but this is not possible to get rid of and it's certainly
a browser bug.

Add KaTeX rendering to Markdown. (#20571)
This PR adds mathematical rendering with KaTeX.

The first step is to add a Goldmark extension that detects the latex
(and tex) mathematics delimiters.

The second step to make this extension only run if math support is
enabled.

The second step is to then add KaTeX CSS and JS to the head which will
load after the dom is rendered.

Fix #3445

* Add new JS linter rules

Adds a few useful rules from eslint-plugin-github. Notable changes:

- Forbid dataset usage, its camel-casing behaviour makes it hard to
  grep for attributes.
- Forbid .then() and .catch(), we should generally prefer await for new
  code. For rare cases where they are useful, a eslint-disable-line
  directive can be set.
- Add docs js to linting

* also enable github/array-foreach

* small tweak
