Subject: [PATCH 1/5] [CI][Github] Add Workflow to Run Python Tests in CI
 Folder

This patch adds a new GHA workflow that runs pytest inside of the .ci
directory to test all of the CI infrastructure. This is to make it more
visible to new contributors that these tests exist and also to ensure
that they are passing before merge. There have been several instances
already where someone neglected to update these tests and we should have
automation to enforce this.
