Update whitenoise to 6.5

There's an encoding issue that affects iOS/Safari and I'm hoping this change resolves it (see whitenoise docs).

This should work. There is no need for the latest version of WhiteNoise (6.6.0) since that would require updating the project's Python version and the iOS/Safari issue was only for WhiteNoise < 5.0.

At some point we do need to upgrade python. It should be painless but will take some verification.

I was looking into this but I don't have experience with Heroku, pre-commit, or tox.

It seems like these are the necessary changes, using python 3.12 as the example:

[tox.ini] envlist = py312,lint
[.pre-commit-config.yaml] language_version: python3.12
[runtime.txt] python-3.12.3
[ci.yml] python-version: "3.7"
[README.md] * Python 3.12+ (I actually don't know if this is necessary?)

I'm still new at all of this, so it might be naive to think changing 5 lines is enough.

That is pretty much exactly what I would do. However I suspect there may be some incompatible dependencies. After trying that upgrade and updating your dependencies things may require some additional changes.
