Problem: Many parsers require node/npm to evaluate the `grammar.js` before being able to generate a parser from it. Solution: Generate from `grammar.json` instead, which is fully resolved. Drops `node` and `npm` as (optional) requirements for nvim-treesitter. Note that this requires parsers to commit the generated json iff the grammar requires evaluation (which is currently the case for all tracked languages).
