Add SC Environment Impact Workflow

Adding a workflow to check for impactful SC environment changes. This
will drop a comment in PRs to notify the author of impactful changes and
notify the rosa core team slack channel. This is non-blocking and
informational to better prevent issues during release week for the
security compliance environment.
