Add License and Requirements to Source Distribtion

[janjagusch]

Description

Hi!

We're currently making an effort to put the responsible-ai-toolbox on conda-forge. You can find the corresponding PRs here:

• add erroranalysis conda-forge/staged-recipes#19439
• add raiwidgets conda-forge/staged-recipes#19449
• add rai-core-flask conda-forge/staged-recipes#19445
• add raiutils conda-forge/staged-recipes#19446
• Add responsibleai conda-forge/staged-recipes#19448

We've noticed that there are some files missing in the source distribution that you ship on PyPI.

• The license is missing
• The requirements.txt file is missing, which is read inside the setup.py (example)

Adding the requirements.txt to the source distribution can be accomplished by adding a MANIFEST.in file to the root of the package repository. As there is no way to reference files outside the root of the repository when building a source distribution (source), we had to copy the license file into all package directories. We also made sure that the dist/ directory does not get committed to version control when testing this.

Checklist

• I have added screenshots above for all UI changes.
• I have added e2e tests for all UI changes.
• Documentation was updated if it was needed.

FWIW we'll have to override the failing CD build since the secret isn't available for people with their own forks (which is also something we should fix at some point). Since there are no real code changes I'm not worried about that, though.

@janjagusch do you need us to do another pypi release, or are you all set to add those packages to conda-forge?

[imatiach-msft]

FYI I force-merged this PR due to the CD build failing, I think this is something that we really need to resolve as soon as possible for those who contribute from forks as it's something that has come up numerous times

Thanks for merging @imatiach-msft! If you could release new versions, that would be great. I can work around the missing files, but this way to build would be much easier. Thanks a lot!
