correcting_rtype_documentation_sphinx

[jposada202020]

well that was a wild ride, not the most elegant solution, but a more standard solution. @lesamouraipourpre now is you turn :) if you could review that would be greatly appreciated 👍🏼

Others Changes:

1. Removing Busio references
2. Adding Product ID
3. Adding product and learning guides to the API
4. Changing CircuitPython Reference from Github to the Website

Documentation built locally and it all looks grand. That's an impressive reworking with all the specific products listed.

I can't believe the solution to the different parameters was as simple as removing the space after the comma. That must have been the only thing I didn't try.

Trust me I ve already gave up, I have even installed the Sphinx, rtype.extension (that works, less effectively) but as I mentioned it was wild. A the end when I was cleaning up for submitting by luck I made the mistake of removing the space. Thanks for reviewing. :)
