Subject: ci: add check for downstream queries

Problem: Parser updates may break downstream queries.

Solution: Add workflow that clones and validates queries in

* https://github.com/nvim-treesitter/nvim-treesitter-textobjects#main
* https://github.com/nvim-treesitter/nvim-treesitter-context

on changes to the parsers.lua table. (Workflow should not be required to
pass; the purpose is to give a heads-up that follow-up PRs are needed.)
