add 'use-grammars' to languages.toml
The vision with 'use-grammars' is to allow the long-requested feature of being able to declare your own set of grammars that you would like. A simple schema with only/except grammar names controls the list of grammars that is fetched and built. It does not (yet) control which grammars may be loaded at runtime if they already exist.
