feat(treesitter)!: use return values in `language.add()`
Problem: No clear way to check whether parsers are available for a given
language.
Solution: Make `language.add()` return `true` if a parser was
successfully added and `nil` otherwise. Use explicit `assert` instead of
relying on thrown errors.
