Updated several missing files per the cookicutter template
close #3600

I think that's a start but there's more. I still think that the better way would be to recreate the project from scratch but if this is easier for you, we should ensure that we do it right.

1. What about the issue templates?
2. What about the hatch test set up?
3. What about the whole CI set up? Yours differs greatly from the template and I'm a bit surprised at the number of workflows that you have.
4. The pre-commit setup needs tons of updates, please.
5. The whole configuration of the linters as well -> please also update the pyproject.toml
6. The RTD setup needs updates
7. There's probably more that I missed...
