CI/CD pipeline 'licenses-latests' fails

What happened:

CI pipeline 'licenses-latest' does not run properly because a new version of the python library Scancode-toolkit was recently released.

What to do:

1. Create a new 'tox' environment to run 'scancode-toolkit'.
2. In the CI/CD pipelines, run this 'tox' environment under Python 3 (and not Python 2.7)
