Libraries: docs/conf.py gives version as "1.0"

All or nearly all the library `docs/conf.py` files contain this:
```py
# The short X.Y version.
version = "1.0"
# The full version, including alpha/beta/rc tags.
release = "1.0"
```
This incorrect `1.0` version does not show up too many places, but it does show up in the HTML `` text, which shows up in search engine results, e.g.:


There are various ways to fix this: https://stackoverflow.com/questions/26141851/let-sphinx-use-version-from-setup-py is one discussion I found.

To fix this would require an all-library patch, and also https://github.com/adafruit/cookiecutter-adafruit-circuitpython needs to be fixed.

Start by reviewing the library docs/conf.py files and the cookiecutter-adafruit-circuitpython template mentioned in the issue. Trace where each library's version and release values should come from, update the relevant configurations across the bundle and template, and verify that generated HTML titles no longer show 1.0.
