Certainly this is not the intended way to get tree-sitter working, at
least in the long term?  I am not up-to-date with tree-sitter
development in general, but is it planned for distributions to package
the grammars and have them installed on a language-level?  I don't
suppose it would make sense for them to be distributed along with Emacs,
or does it?
