Docs generation is now `python -m buildconfig docs` and `python -m buildconfig docs full_generation`

[oddbookworm]

I didn't want to have to invoke a specific python file every time I generate docs, so here's a useful helper

[oddbookworm]

When running it from setup.py it says Please use the following replacement: D:\Programs\Python312\python.exe buildconfig docs full_generation but running that command raises ImportError: attempted relative import with no known parent package as the suggestion is missing '-m'. Other than that, I like this helper

Oops, it's fixed now
