✨ Add support for Python 3.12

[ldericher]

I strictly followed Commit 4576c83 to create this.

If you want, I can add commit(s) for release notes, but I don't want to steal your fun part 🤣
If you want to follow upstream lifecycle, you might want to also phase out support for python 3.7.

Tag me if you need more commits here.

Thanks for the interest! 🍰

Now that Uvicorn supports managing workers with --workers, including restarting dead ones, there's no need for Gunicorn. That also means that it's much simpler to build a Docker image from scratch now, I updated the docs to explain it.

Because of that, I deprecated this Docker image: https://github.com/tiangolo/uvicorn-gunicorn-docker#-warning-you-probably-dont-need-this-docker-image

Given that, I'll now close this one, but thanks for the effort! ☕
