chore: update version

Updates the tree sitter version from 0.22.6 to latest (0.26.3). Note
that the tree sitter ABI has changed between the two of these. As such,
we currently explicitly ask for the 0.22.6 ABI, which is v14. Moreover,
some flags have changed because tree sitter has moved to a specific
config file, `tree-sitter.json`, which we haven't yet moved to. The main
implication for us is that the `--no-bindings` flag has been removed and
should now be controlled through this config file.
