Clean up python 3.8 leftovers

[DoctorJohn]

Description

This PR is a micro follow-up to #3730 and contains essentially the diff of Thiago's PR and a Python 3.9 upgrade branch I was working on. The diff amounts to the update of one 3.8 reference in our docs and the removal of an now unnecessary version constrain.

Hi, thanks for contributing to Strawberry 🍓!

We noticed that this PR is missing a RELEASE.md file. We use that to automatically do releases here on GitHub and, most importantly, to PyPI!

So as soon as this PR is merged, a release will be made 🚀.

Here's an example of RELEASE.md:

Release type: patch

Description of the changes, ideally with some examples, if adding a new feature.

Release type can be one of patch, minor or major. We use semver, so make sure to pick the appropriate type. If in doubt feel free to ask :)

Here's the tweet text:

🆕 Release (next) is out! Thanks to @NucleonJohn for the PR 👏
