Transition to new Carpentries workbench

[milanmlft]

Hi there!

During the CarpentryConnect 2024 mini-hackathon led by Matt Bluteau (@bielsnohr) and Aleks Nenadic (@anenadic) we transitioned this lesson to the new lesson format: the carpentries workbench 🎉

You can find a fork of this lesson using the workbench here: https://github.com/milanmlft/machine-learning-trees-python
You can checkout the new flashy version of your lesson here: https://milanmlft.github.io/machine-learning-trees-python/

There are only a few next steps to complete the transition:

1. Merge or close any open pull requests on the lesson repository
2. Publish your lesson to Zenodo, to create an archive of the last styles version of the site. (This is currently documented at https://carpentries-beta-handbook-preview.netlify.app/resources/curriculum/lesson-release#publishing-the-lesson-on-zenodo but that address will change when the new handbook is launched next month.
3. Clone your “Workbenchified” fork of your lesson
4. Use git remote set-url origin <address of your lesson repository on GitHub> so that the changes can be pushed up to your GitHub repo
5. Follow the documented workflow from point 4.3 onwards. (Points 4.1 and 4.2 should have been taken care of)

Let me know if you need help!
