Remove explicit support for OCI model serving compatibility

[emilys314]

towards [RHOAIENG-14748] enable connection types feature

Description

After review and discussion from Jeff DeMoss, we decided to remove the OCI ootb connection type, because it's not fully supported yet. Many OCI model registries may require authentication, and requires additional kserve support before being usable (https://kserve.github.io/website/latest/modelserving/storage/oci/#enabling-modelcars)

How Has This Been Tested?

• Make sure there are no references to "OCI" in the connection types admin page
• The ootb OCI connection type will also no longer exist (but you'd have to do this manually on your cluster if you already have it)
  • And fyi it will still show up in model serving as a "URI" compatible type

Test Impact

• tests updated for removing OCI

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit or cypress tests for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change.

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main

Updates LGTM @emilys314 ! Deleted the oci-compliant-registry-v1 configMap from the shared cluster as discussed since it was showing up in the connection types list by default. No longer showing in the connection types list as expected.

"Model serving compatible type" dropdown looks good too and no longer references OCI registry.

[mturley]

LGTM. Tested locally against the ods-qe-psi-08 cluster. I temporarily scaled down the operator in order to delete the oci-compliant-registry-v1 configmap and verified that it is not an option in model serving or the connection types page.
