fix(treesitter): enforce lowercase language names (#28546)

* fix(treesitter): enforce lowercase language names

Problem: On case-insensitive file systems (e.g., macOS), `has_parser`
will return `true` for uppercase aliases, which will then try to inject
the uppercase language unsuccessfully.

Solution: Enforce and assume parser names to be lowercase when
resolving language names.
