autobuild nox image on new release about tools

[nilsdebruin]

Hi Kevin!

I am happily making use of your Nox Docker build and read this issue! I am also still searching for something similar you are describing; creating automated builds when versions change including tagging. That would be really awesome! In case I find something useful I will let you know!

Solved via autobuilding on master, tagging the image based on parsing the requirements file and then having renovate autoupdate the requirements file

In a shocking display of low-tech automation, I've subscribed to release notifications on the upstream repo and am using myself as a webhook. It would still be great to work on a bit more in the way of automation.

Hi @TheKevJames,

Thanks for putting together this nox Dockerfile. I have used it in a project.

I have cloned your repo and put together a relatively simple way of automating the nox version upgrade and opened a pull request for you.

Let me know what you think or if it needs any tweaks.

Cheers!
Sean
