querySelector
As per https://github.com/go-gitea/gitea/pull/30115#discussion_r1626060164, prefer `querySelector` by enabling [`unicorn/prefer-query-selector`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/main/docs/rules/prefer-query-selector.md) and autofixing all except 10 issues. According to [this](https://old.reddit.com/r/learnjavascript/comments/i0f5o8/performance_of_getelementbyid_vs_queryselector/), querySelector may be faster as well, so it's a win-win. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: Giteabot <teabot@gitea.io>
