Dask has stopped support for 3.7

Maybe it's time we do too?

Brings in nice typing things, walrus operators :=, f"{value=}" debug strings if we do :)

I'm still struggling on this with the fact that google colab only runs Python 3.7. As colab is a go-to place for easy online experimentation, I would like to keep this for now. Maybe we could ask the scikit-learn devs how they cope with this issue?

It's not just dask, it's quite a bit of the Python scientific ecosphere is moving away from Python 3.7, one example is scipy in which there was the recent errors with kurtosis which is probably related to numpy dropping support too.
