Should not we just update matplotlib to again be compatible to pyiron_atomistics? From my perspective we can now disable python 3.8 on pyiron_contrib and then we should be able to update the open dependency bot pull requests.

https://github.com/conda-forge/matplotlib-feedstock/blob/main/recipe/meta.yaml seems to still have pyparsing constraint.

https://github.com/conda-forge/matplotlib-feedstock/blob/main/recipe/meta.yaml seems to still have pyparsing constraint.

The issue is that these constraints were only introduced in matplotlib =3.7.2 so by removing Python 3.8 support and updating matplotlib to 3.7.2 we should be able to spot the issue here in this repository before we make a new release.

Looks good to me
