Gitlab container registry need to support fleet media types, fleet cannot push OCI artifact to Gitlab container registry, unknown media type: application/fleet.manifest
We are experiencing an issue when pushing an OCI artifact from Fleet (Rancher) to the GitLab Container Registry.
The push operation fails with the following error:
```
Failed to perform "PushReference" on destination:
PUT "https://custom_gitlab_domain/v2/sre/packages/ocistorage-gitlab/s-73dde7ead2b1dd47871badfd6ce954f78addd5c0bfa8fc65bb00c6b379477/manifests/latest":
response status code 400:
manifest invalid: manifest invalid: unknown media type: application/fleet.manifest
```
It appears GitLab container registry rejects the manifest due to an unsupported media type:
```
application/fleet.manifest
```
