Editing an approved Change Request does not invalidate approval

Describe the bug

When a change request has been approved the creator can edit the change request and still publish it without re-requesting approval. Editing an approved change request should invalidate the existing approval and require re-approval before publishing.

Steps To Reproduce

1. Create a change request
2. Have a colleague approve it
3. Edit the change request after approval
4. Observe that the Publish action is still available without re-approval
5. Publishing succeeds despite the post-approval edit

Expected behavior

It should not be possible to edit an approved change request (even if it was approved by 1 of N required approvals - the moment it has 1 approval it cannot be edited anymore)
