Sleeper CLI Docker images on main branch can't be pulled

[patchwork01]

Description

After a while, Docker images built against the main branch seem to become unavailable to pull. We get manifest unknown from a docker image pull even when the image is visible on GHCR with the specified tag.

Here's a GitHub community discussion on this problem, which seems to be a bug in GitHub:

• https://github.com/orgs/community/discussions/56237

Steps to reproduce

1. See image displays as existing in GitHub at https://github.com/gchq/sleeper/pkgs/container/sleeper-deployment/195478646?tag=0.22.1
2. Run docker image pull ghcr.io/gchq/sleeper-deployment:0.22.1
3. See mainfest unknown failure
4. See download count incremented in GitHub UI, and does each time you run docker image pull, even with the failure
5. Run docker manifest inspect ghcr.io/gchq/sleeper-deployment:0.22.1
6. See manifest unknown failure

Expected behaviour

Images should stay available for download indefinitely while tagged.

Background

This causes:

• Update Deployment of Sleeper CLI Documentation  #2479

On hold as I've raised a support ticket with GitHub.

[patchwork01]

No longer on hold as this should be resolved by the following issue:

• Only build Sleeper CLI Docker images against develop #2857
