feat(treesitter): add injection language fallback (#24659)
* feat(treesitter): add injection language fallback
Problem: injection languages are often specified via aliases (e.g.,
filetype or in upper case), requiring custom directives.
Solution: include lookup logic (try as parser name, then filetype, then
lowercase) in LanguageTree itself and remove `#inject-language`
directive.
