Use scripts instead of notebooks for tests

[psschwei]

Summary

Run tests against python scripts instead of jupyter notebooks

Details and comments

There's two reasons for doing this:

• we're going to be moving the docs out of this repo in Docs: move docs to IBM docs #1166 , so we'll need something to test against once that happens
• we get more granular logs on each job (rather than just a blanket pass/fail), which will partially help with things like Docker notebook test doesn't detect notebook execution failure #1094

Note that the decorators test fails (xref #1238)

We also now see all the warnings when the LocalProvider tries to use unimplemented file methods : https://github.com/Qiskit-Extensions/quantum-serverless/actions/runs/8177774823/job/22360183087?pr=1239

Oh wow, good refactorization @psschwei . Is it ready for review or are you testing something more?

Ready for review 😄

Do you update this pull request with the last change fixing the decorator, @psschwei ? I can take a look into this tomorrow 🙏

[psschwei]

I'll rebase now

I like the idea of the pull request. My only comment @psschwei is if you could check if we can remove nbmake dependency with this from the requirements:

I think we don't need it with these last changes but I'm not sure 😅

Thank you, @psschwei ! LGTM 😄
