Locals highlighting also highlights path elements

[lovelymono]

Identifiers that are part of the path also get highlighted with @local.reference if there's a parameter with the same name.

If I understand this correctly, this happens because the Rust grammar assigns identifier node to path elements:

["source_file", "impl_item", "declaration_list", "function_item", "parameters", "parameter",
 "scoped_type_identifier", "scoped_identifier", "identifier"]

and the queries/rust/locals.scm is simply:

(identifier) @local.reference

This might be a bug in tree-sitter-rust, rather than Helix, but right now it produces less than pleasant looking outcomes, especially with a theme that highlights parameters in bold.
