Subject: [PATCH] Drop Python 3.9 support (#1377)

Contributes to https://github.com/rapidsai/build-planning/issues/88

Finishes the work of dropping Python 3.9 support.

This project stopped building / testing against Python 3.9 as of https://github.com/rapidsai/shared-workflows/pull/235.
This PR updates configuration and docs to reflect that.

## Notes for Reviewers

### How I tested this

Checked that there were no remaining uses like this:

```shell
git grep -E '3\.9'
git grep '39'
git grep 'py39'
```

And similar for variations on Python 3.8 (to catch things that were missed the last time this was done).
