flake: use builtins.fetchTree to shallow-clone grammar repos
Here we perform a shallow fetch using builtins.fetchTree. In order to make this work, we need to specify the `ref' for any repository that doesn't have `master' as its default branch (I'm not sure why this limitation exists since we don't need this when performing the shallow fetch in `--grammar build') This `ref' field is ignored by helix, so I have left it undocumented for now, but I could be open to documenting it.
