Patch releases for #107 (Add `kube-system` namespace exception to all constraints that cause violations)

For Big Bang release 1.12 using "deny" constraints, patch with #107 (closed) fix.

To do this, here is what you need to do:

• Go get BB release version X
• Find out the version of OPA Gatekeeper it was using and perform a git checkout on that version
• Identify if any of the constraints are set to "deny". If not, you are done. Otherwise, continue
• Create a branch in OPA Gatekeeper off the legacy version
• Cherry pick the commits from #107 (closed) into OPA Gatekeeper. It should be changes to values.yaml and config.yaml
• Create a draft MR and test it.
• Once it is tested, request that a tag be created on your branch. Do not merge to main.
• Once the tag is created, request the branch and MR be deleted. The tag will make sure the commit remains
• Create a branch for BB release version X
• Update the BB branch to use the new OPA tag
• Create a MR into the release branch and test it.
• Request a BB owner to create a release on the MR.
