Improve tsq/tree-sitter-query language support

[uncenter]

WIP adding support for tree-sitter query files (scheme-like), using https://github.com/tree-sitter-grammars/tree-sitter-query for the grammar and https://github.com/ribru17/ts_query_ls as the LSP.

Todo

• LSP
• Reverse query order for precedence order difference

You can update the existing entry for this language instead:

helix/languages.toml

Lines 1439 to 1449 in b1bdbc6

	[[language]]
	name = "tsq"
	scope = "source.tsq"
	file-types = ["tsq"]
	comment-token = ";"
	injection-regex = "tsq"
	indent = { tab-width = 2, unit = " " }
	[[grammar]]
	name = "tsq"
	source = { git = "https://github.com/the-mikedavis/tree-sitter-tsq", rev = "48b5e9f82ae0a4727201626f33a17f69f8e0ff86" }

That language is set to recognize .tsq files as a dummy value. (We didn't want the tree-sitter query language to be used over Scheme generally.) The file-types you have proposed here instead looks better though, there might still be some overlap with regular Scheme files but it seems unlikely.

I might be messing something up but it seems like I can't leave the name as tsq, it only works when I use the grammar name query.

You may need to set grammar = "query" in the [[language]] entry for tsq. The [[grammar]] entry's name is used for loading the parser so it needs to basically match the name attribute from the grammar.js https://github.com/tree-sitter-grammars/tree-sitter-query/blob/a6674e279b14958625d7a530cabe06119c7a1532/grammar.js#L16
