Python [PEP-585](https://peps.python.org/pep-0585/) replaces a number of
`typing` module types with built-in equivalents and `collections.abc`
versions as of Python 3.9, with the aim of eventually removing the
`typing` module versions of these classes altogether. Since the minimum
required version of Python listed in the [Contribution Tools
document](https://github.com/carbon-language/carbon-lang/blob/trunk/docs/project/contribution_tools.md#main-tools)
is 3.9, the type hints in the various python files in the repo can be
updated to this style of type hint without a need for backwards
compatibility.
Feel free to close if this isn't a desired change at this time!

Where there was an object initialization immediately followed by
assignment I condensed it to one line, which seems to be the convention
looking at other files. I also deleted the repetition of 'of' in some
c++ comments because it was grammatically incorrect.

In Python 3.x it is not necessary to have `object` inheritance in classes, it may be useful to have `object` inheritance in classes if the code has support for Python 3.x, 2.x, but currently the present code does not contain support for python 2.x.

I'm treating my PR to mypy bazel integration as dead in the water. Abandoning that approach, this seems to work reasonably well as a replacement. It's actually a slightly newer version of mypy too -- the bazel integration was stuck on an old version.
Note I don't think we're losing much: we shouldn't be writing too much python.
Now that we've centralized on a monorepo, tidy up some lingering
references.
For the `pr_comments.py` script, I've left the flag in place to select
a repository as it seems useful functionality to have available even if
we don't expect to need it in the near term. That said, I can pull it
out if folks prefer.
I haven't updated any of the *proposals* because it seems better to
leave those as-is from when they were written. The references seem
unlikely to be confusing to me. Happy for suggestions if needed there
though.
