RSDK-8440: fix license finder

[purplenicole730]

Based on the available logs, this workflow has been failing for at least 3 months. Before that, the git logs have been removed, so we're not sure when the failure started.

license_finder has some issues with Python version 3.12, so now the workflow is using 3.11.5.
In the workflow, the command to run license_finder was changed so that errors fail the workflow instead of letting it succeed.

Things I tried that didn't work, wasn't the best solution, or introduced more errors:

• pip install six doesn't change anything
• pip install pip==22.0 introduces another error
• pip install pip==23.0 introduces another error
• pip install pip==20.0.2 introduces another error
• pip install pip==9.0.0 introduces another error
• curl -sS https://bootstrap.pypa.io/get-pip.py | python3 doesn't change anything
• python version 3.11 doesn't change anything
• pip install pyenv doesn't change anything
• /opt/hostedtoolcache/Ruby/*/x64/lib/ruby/gems/*/gems/license_finder-*/bin/license_finder_pip.py requirements.txt doesn't actually run license_finder
• poetry run license_finder --python-version=3 fails even after using python v3.11.5
• poetry run license_finder fails even after using python v3.11.5

I think we need to invoke this via python3. It looks like in the failed jobs it's python3 /path/to/license_finder_pip.py /path/to/requirements.txt, and in successful runs in other SDKs the output is different from here (it should say All dependencies are approved for use).

Let me try that!

You're absolutely right about the expected output! Using python3 was not the method since the problem was the script itself, so I fixed it. Thanks for catching that!

Nice! Looks good and the license_finder check succeeds 🎉
