This

• removes the HTML generator entirely
  • I could put it back but I didn't feel like figuring out reuse-compliant license statements for it
  • but I don't think we're going to use it?
• moves the python code up a directory level
• adds pre-commit and fixes pre-commit compliance (reuse, black, pylint)
• adds the .circuitpython.skip tag to avoid generating an image for ourselves

With the scrips in the root of the repo this is now one level off in my environment, so ../Adafruit_Learning_System_Guides/ is the value I use now.

But this is dependent on the environment it's running in and may end up needing to change again when it's setup with the CI, I'm going to merge it for now. Perhaps when running in CI there is some other way it can access the repo that it's running inside of

Ah, actually I just noticed this is an environment variable now and the string given I guess is the default used if it's not present. So the hardcoded value doesn't need to change on different environments.

Thanks for all of these improvements!
