Restore Docker image annotations and fix attestations (#14165)
More follow-up to #13459
- Depot doesn't support annotations, so we push those manually
- Docker push for the re-tag was breaking the manifest, since we need to
annotate manually, we just do that instead
- We attest after the annotation
A bit of an aside
- We test building the extra images, it's very fast and I don't see why
it's better to gate it
I tested this on my fork then cleaned it up a bit for a commit here. You
can see the images at
