Remove overzealous index deletion assertion.
A broken HOT chain is not an unexpected condition, even when the offset number points past the end of the page's line pointer array. heap_prune_chain() does not (and never has) treated this condition as unexpected, so derivative code in heap_index_delete_tuples() shouldn't do so either. Oversight in commit4228817449
. The assertion can probably only fail on Postgres 14 and master. Earlier releases don't have commit3c3b8a4b
, which taught VACUUM to truncate the line pointer array of heap pages. Backpatch all the same, just to be consistent.
