Fix gitlab grack to use our own repositories
What does this MR do?
Since the default grack-project (https://gitlab.com/gitlab-org/gitlab-grack) uses an unsupported Git protocol with GitHub for it's simplegit (https://github.com/schacon/simplegit) submodule we moved both projects to https://gitlab.com/gitlab-org/ci-cd/gitlab-runner-pipeline-tests/gitlab-grack and https://gitlab.com/gitlab-org/ci-cd/gitlab-runner-pipeline-tests/simplegit. Simplegit is not a fork or clone, it has just a README.
Why was this MR needed?
We stared getting errors in our pipelines https://gitlab.com/gitlab-org/gitlab-runner/-/jobs/1739633860#L3146
fatal: remote error:
The unauthenticated git protocol on port 9418 is no longer supported.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.
What's the best way to test this MR?
Tests should pass
