Move to using minio official docker image

[cooperlees]

Right now we use a fork to run minio for CI: https://github.com/pypa/bandersnatch/blob/main/.github/workflows/ci_ubuntu.yml#L21

Lets see if we can:

• Pass arguments to use image as is
  • Maybe there is a way today I just didn't find
• Add a second ENTRYPOINT script that starts an anonymous minio server (Merge to upstream repo)
• If they won't accept, maybe create our own fork of the main and possibly automate keep the image up to date

Passing arguments is not feasible for now, There's no clean way to do it. https://github.community/t/job-service-command/16477

merge to minio image ? not so feasible too....

maybe we can try this https://docs.github.com/en/actions/creating-actions/dockerfile-support-for-github-actions dockerfile steps. according to the document, we can just write a Dockerfile, with base minio/minio:latest and set the entrypoint and cmd.

Sweet - #1087 works as the Github Actions ubuntu has docker installed and ready to be used like in that PR. So we can run the minio container via docker run in a step as it's backgrounded.

It's a bit of a race, but we don't start testing s3 first so we have a bit of time ... :)
