Pull Request checklist

Attempt fix for #419 as reported by @schlunma

@LisaBock @rswamina @hb326 this also fixes the issue with the disallowed string format and I cranked up the max line length so the checker stops failing.

Before you start

• Read CONTRIBUTING.md.
• Create an issue to discuss your idea. This allows your contributions to be incorporated into the tutorial.

Tasks

• Give this pull request a descriptive title.

• If you are making a new episode, please make sure the content conforms to the Lesson organization and Lesson formatting sections in CONTRIBUTING.md and does not contain any spelling or grammatical errors.
• Preferably Codacy checks pass. Status can be seen below your pull request. If there is an error, click the link to find out why.
• Preview changes on your machine before pushing them to GitHub by running make serve, alternatively make docker-serve. Please see the Previewing your changes locally section in CONTRIBUTING.md for installation instructions.
• All code instructions have been tested.

Did you try this locally with a fresh conda environment? I don't trust the CI tests on this one. As far as I can tell, the actual deployment of the website does not use a conda environment, so we need to test that this actually works within an environment.

no, I was hoping you would, since you already have the conda env that exposed the problem in the first place. Lemme know if you strapped for time, I can test it meself 🍺

alas, ideally, we should include a GHA that run exactly that, so we catch an issue early on - if you give me the command sequence, I can pop a workflow in here

I did what is described here: https://github.com/ESMValGroup/ESMValTool_Tutorial/blob/main/CONTRIBUTING.md#previewing-your-changes-locally

cd ESMValTool_Tutorial
mamba env create -f environment.yml -n tut
mamba activate tut
make serve

With your changes, I get this now:

$ make serve

OK thanks, Manu! I'll take it from here then - it's not as easy as I initially thought then
