All checks were successful
continuous-integration/drone Build is passing
Fix 'nix flake check'
Turns out that 'tree-sitter' is not wrapped to have node and a compiler
available, because nixpkgs assumes that grammars already include
generated files.

So wrap it manually and use that in our pre-commit/checks.
