Update TSQ queries

[the-mikedavis]

A few changes to make TSQ highlights better:

• A parsing error has been fixed in the grammar itself
  • Previously tree-sitter-tsq did not parse the variables
    in predicates like (#set! injection.language "javascript")
• Theme nodes as tag
  • The newly added node to the parser (from the above fix) is
    variable which takes over the variable capture from nodes
• Highlight known predicates as function and unsupported
  predicates as error
  • This may help when translating queries from nvim-treesitter.
    For example #any-of? is a common one used in nvim-treesitter
    queries but not implemented in Helix or tree-sitter-cli.
• Inject tree-sitter-regex into #match? predicates
