languages.toml: update tree-sitter-rust to latest

[m4rch3n1ng]

notable changes include:

• parse default const parameters tree-sitter/tree-sitter-rust#255, which changed how type parameters work and which was a breaking change.
• parse use bounds (precise capture syntax) tree-sitter/tree-sitter-rust#252, which makes the hot patch in dca235c obsolete, as upstream tree-sitter helix can now properly parse use bounds.

additionally i also added (shebang) as an @comment.

should this be (type_parameters (type_parameter name: (type_identifier) @type.parameter)) ?

[m4rch3n1ng]

could be, but i don't really see the benefit of that. a (type_parameter can currently only appear inside of a (type_parameters, so it doesn't matter, but why unnecessarily restrict that?

additionally, previously the (optional_type_parameter was also only queried like that and it wasn't a (type_parameters (optional_type_parameter ....

does hx --grammar fetch and hx --grammar build fix that? to me it looks like your grammars are out-of-date while your queries are up-to-date.

aha yep that worked
