Add CI job for spelling and grammar checks
Would be great to see something like https://github.com/subosito/gingerice in CI for spelling and grammar checks.
In gingerice's case, I think we could create rubocop, haml_lint and eslint linters that process text nodes (not so straight forward) through gingerice. Maybe there is an existing package out there.
Or, maybe a simple solution is to run it on our locale/gitlab.pot file. You would only really get as much coverage as our i18n linters as they face the same "text node" detection complications, so it might as well use that file.
