[Task]: Back-end license checking

[daphnegold]

Summary

The proposed back-end license checking tool, license-check, needs to be configured. It's unclear if the license verification is robust enough to meet our needs regarding automation.

Acceptance criteria

• Check that pip-licenses is robust enough to automatically verify licensing checks (if not, consider another tool like liccheck)
• If a different tool is chosen, update ADR [ADR]: Back-end Code Quality Tools #101
• Configure Github Actions to run automatically

Open Questions or Notes

• This helps to ensure all the licenses are good and check automatically.
• What is the driving request behind this? What does a good outcome for this look like? Is it enough to ask, we want to use this new library, would that work? @acouch
• Exclude certain licenses that are incompatible with open source.
