This includes building the binaries, building and pushing the docker images
to Dockerhub, and updating deployment-tools so tempo-dev-01 uses the latest images.

I've tested the steps except for docker push and the deployment-tools update: https://github.com/grafana/tempo/actions/runs/12596510374/job/35107743009?pr=4501

This looks sane and I don't think it's worth digging into all the details. It will either work or it won't :)

Let me know when you're ready to merge.

I do not have permission to merge as it's a branch in the upstream repo, so please merge at your convenience.

We will then see if the docker push and the deployment-tools update work, if not we can revert it.
