Add Dockerfile for Python script

[luigigubello]

This PR adds a Dockerfile for the Python script validator-and-generator.py. This should partially solve #33

[luigigubello]

@eddie-knight can you try to run the script now?

[eddie-knight]

Testing this now.

Regarding the documentation update, may I recommend that we change to utilizing the GitHub vulnerability reporting tooling for this repo? (security tab at the top)

[eddie-knight]

The containerization works as intended! I didn't get very far in testing the functionality, but that can be improved in follow-up PRs if needed.

[eddie-knight]

My only request before merge is that we do the full reorganization (file-creation and file-deletion) in the same PR. Currently this will result in two copies of the python code in the main branch.

Oh right, this was definitely not intended.

Yes, good point. We have the private vulnerability reporting enabled, I will also add a SECURITY.md in a different PR.
