Creating a toolchain for Python 3.11

[flatsiedatsie]

I'm trying to create a Python 3.11 addon with the Github workflow, but the process fails.

Unable to find image 'webthingsio/toolchain-linux-arm64-python-3.11:latest' locally
docker: Error response from daemon: pull access denied for webthingsio/toolchain-linux-arm64-python-3.11, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

I assume that there simply is no toolchain for Python 3.11 yet. My question:

Would you be willing to generate one?
If not, could you point me in the right direction to try building it myself?

I've created a pull request that:

• adds Node 16 and 18
• updates python 3.9
• adds Python 3.10 and 3.11
• changes Buster to Bullseye
