feat(github-action): Add with keyword

This is a follow-up to SchemaStore#1803 where `uses` was added. `with` is also allowed. I am not sure how to define the constraint where `with` can only be used when `uses` is defined.

See https://github.blog/changelog/2021-08-25-github-actions-reduce-duplication-with-action-composition/ for more information
