Is your feature request related to a problem?
I'm using single registry for both my container and helm charts stored in OCI format. I'd like also to use single secret for pulling my images and configuring Helm OCI Registries in fleet.
Solution you'd like
In addition to basic-auth and ssh-auth, allow spec.clientSecretName in GitRepo resource to be in dockerconfigjson type.
Alternatives you've considered
It is possible to use basic auth to pull helm charts from OCI registry.
Anything else?
