Enable on cluster resolution of gitea OCI container registry

[jessesanford]

Gitea now has implemented my x-forwarded-for fix for the AppURL resolution in 1.22.0. See Discussion here: go-gitea/gitea#29591 and the fix here: go-gitea/gitea#30891 ... while it is not in the release notes for 1.22 you can see that it was merged into that release branch at go-gitea/gitea@d4c2db3

Let's bump the gitea version to 1.22+ so that we can make use of the oci registry on cluster.

PR #166 partially fixes this.

As part of fully addressing this issue, we should also provide documentation on using the local registry and potentially making use of it where possible.

Using v0.6.0, I got a cert error when I perform a docker login

docker login -u $GITEA_USERNAME -p $GITEA_PASSWORD $GITEA_REGISTRY
Error response from daemon: login attempt to gitea.cnoe.localtest.me:8443 failed with status: authenticating creds for "gitea.cnoe.localtest.me:8443": pinging container registry gitea.cnoe.localtest.me:8443:

Such an error will also take place if a an image is build using a Tekton pipeline and pack CLI
