does anyone else find this section of the docs a little odd?
https://tree-sitter.github.io/tree-sitter/cli/init.html#example
i've only found one tree-sitter.json file that has a tree-sitter array -- most (all?) other tree-sitter.json files seem to have a grammars array.
also, the name key doesn't appear to be mentioned in the same page of the docs -- and iiuc one can get warnings without it (may be it's semi-required?).
