Problem: In some cases, when treesitter is enabled, deleting a
line below virtualtext will not refresh all updated lines.
https://github.com/neovim/neovim/issues/33358

Solution: Revert a part of https://github.com/neovim/neovim/pull/31324
to ensure that the full range (with virtual lines) is refreshed.

Problem: repeated gO in markdown etc. adds extra toc indentation

Solution: don't memoize heading table which gets modified

Remove the `set_timeout` functions for `TSParser` and instead add a timeout
parameter to the regular parse function. Remove these deprecated tree-sitter
API functions and replace them with the preferred `TSParseOptions` style.

Simplify the logic for retrieving the injection ranges for the language
tree. The trees are now also sorted by starting position, regardless of
whether they are part of a combined injection or not. This would be
helpful if ranges are ever to be stored in an interval tree or other
kind of sorted tree structure.

This commit also gives an internal documentation description for
`TSNode:__has_ancestor()`.

Problem:
gO always says "Help TOC".

Solution:
Use a generic title instead.

This matches the `iter_captures` functionality to the `iter_matches`
functionality, allowing it to specify a match limit and start depth for
the query iterator.

Problem: Cannot disable individual captures and patterns in treesitter queries.

Solution: 
* Expose the corresponding tree-sitter API functions for `TSQuery` object. 
* Add documentation for `TSQuery`.
* Return the pattern ID from `get_captures_at_pos()` (and hence `:Inspect!`).

Problem: `InspectTree` error on buffer without ts parser attached.

Solution: show a more correct warning.

Problem:
  :checkhealth vim.treesitter sorts parser entries solely by path,
  splitting duplicates and reducing clarity.

Solution:
  Sort entries first by name, then by path, so that duplicates are grouped.
