When running the mirror-images step from within the release-image workflow
we receive error messages such as
> msg="Failed to sync" target=ghcr.io/continuwuity/continuwuity:v0.5.0-rc.7
> source=forgejo.ellis.link/continuwuation/continuwuity:v0.5.0-rc.7
> error="failed to send blob post, ref
> ghcr.io/continuwuity/continuwuity@sha256:74976f7b85018b5abd867333bc783c7230d985a4b0af595bbf55964e25afe6ef:
> unauthorized"
So, we will need to define our credentials in the release-image workflow too
it seems, when we pull in the mirror-image workflow.
This is a test by adding all credentials that are defined in mirror-images.yml
Probably we don't need them all, but if this does not work, the whole approach
is flawed and we can remove everyting again.
If it works, we should remove unneccessary credentials until we found the
required ones.
