[🚀 Feature]: Auto-generate the Python API from the code

[emanlove]

Feature and motivation

Some recent improvements have been made to the generation of the Python API documentation. Now the Python API doc is generated from the py/docs/source/api.st "template". Taking this a step further we should be able to generate the API from just the code itself. This is important as any updates to the code, for example recent additions with selenium.webdriver.common.bidi, needs to be manually added to this api.rst file, as shown here

Webdriver.common
----------------

.. currentmodule:: selenium.webdriver.common
.. autosummary::
   :toctree: webdriver

   selenium.webdriver.common.action_chains
   ...
   selenium.webdriver.common.bidi.cdp
   selenium.webdriver.common.bidi.console
   selenium.webdriver.common.bidi.script
   selenium.webdriver.common.bidi.session

And if we forgot to add, say selenium.webdriver.common.bidi.script, then it would be missing from the doc. So it would be good to either fully auto-generate it or have some automatic method to check for completeness and changes.

Usage example

Might add a step to the tox.ini to autogenerate the api doc from the code or check for completeness.

I'm assuming we don't want to import a library for this correct? so to minimize dependencies

[emanlove]

@shbenzer, I believe it can be done with the current sphinx build process without any additional packages. I am open to suggestions on other ways to do this.

This would be a nice feature, and we did run into this situation recently. Some new modules were added, but api.rst wasn't updated, so they were missing from the docs until I manually updated it.

I haven't really looked into it, but any suggestions for auto-generating the docs without declaring modules in api.rst would be welcome.

I just implemented this in #15822
