fix(treesitter): raise ts_match_limit to 256 (#22497)

Problem: Some complex queries may not return all matches.

Solution: Raise `ts_match_limit` from current 64 (twice the original
default) to 256 (which Helix uses, and seems to be enough for the reported
problematic cases).

If this leads performance regressions in other queries, we should add a
generic querying timeout instead of relying on a low value here.
