Run new container image tests before publishing

[vyadh]

See test file added in this PR.

I had to split the build and push to ensure we were not pushing any images that had failing tests, as per the recommendation from Docker here.

Thanks, let's give it a try

@hustcer Can you pull those images? For some reason they seem missing, despite copying the GHCR command, and I'm not sure what's wrong.

For the ones generated from my fork, I get:

❯ docker pull ghcr.io/vyadh/nushell:0.99.1-alpine
0.99.1-alpine: Pulling from vyadh/nushell
Digest: sha256:8bd374adb5910b95829eb09554ec41932a3ad0520ab2c45beba038a6cfc9fc87
Status: Image is up to date for ghcr.io/vyadh/nushell:0.99.1-alpine
ghcr.io/vyadh/nushell:0.99.1-alpine

However, for the official ones, I get:

❯ docker pull ghcr.io/nushell/nushell:0.99.1-alpine
0.99.1-alpine: Pulling from nushell/nushell
manifest unknown

Any ideas?

@vyadh Thanks for reporting this issue, it was caused by the image cleanup step, and it should work now after commit: 8bdac9e

[vyadh]

Great, thanks @hustcer, that works perfectly now :)

@vyadh The tests failed here: https://github.com/nushell/nightly/actions/runs/12460106286

[vyadh]

Thanks for the heads up @hustcer - I see you've fixed them already. Much appreciated. I had those invalid signatures all over my code, I should have remembered that might have been here too!

@vyadh 🤣 Feel free to enhance the existing code at any time.
