flux bootstrap doesn't support oci repositories

[btrepp]

Describe the bug

I had just discovered the OCIRepository capability, which seems nice as I can 'render' manifests if needed, rather having being the state completely be rendered in git, and was looking at changing everything over to OCI, so I don't have to maintain SSH-keys.

In doing that, I was going to upgrade flux, which needs to call flux bootstrap. However it seems that OCI isn't an option here.
Even upgrading via bootstrap seems to perform a lot of cloning etc steps, so it's tricky to even work around and force flux to just use OCIRepositories, rather than git itself (it might feel I am going against gitops, by avoiding git :)).

It's way more complicated for bootstrap, but is there any other ways to upgrade without bootstrap?. I can probably tweak the repository to be an OCI repo, but I suspect bootstrap will forever be broken for me that way.

Steps to reproduce

flux bootstrap
The bootstrap sub-commands push the Flux manifests to a Git repository
and deploy Flux on the cluster.

Usage:
  flux bootstrap [command]

Available Commands:
  bitbucket-server Deploy Flux on a cluster connected to a Bitbucket Server repository
  git              Deploy Flux on a cluster connected to a Git repository
  gitea            Deploy Flux on a cluster connected to a Gitea repository
  github           Deploy Flux on a cluster connected to a GitHub repository
  gitlab           Deploy Flux on a cluster connected to a GitLab repository
  

Expected behavior

OCI Repository is an option

You can use the Flux Operator and setup Flux with OCI as single source of truth, docs here: https://fluxcd.control-plane.io/operator/flux-sync/#sync-from-a-container-registry
