Unpin pip (and snakemake)

I think the reason for failure with snakemake 7.30.2 was that you had pip pinned - not quite sure why. Let's try this way - it should then work also with newest snakemake again, and older ones.

Seems to work, I tested with micromamba (works quite nicely and allows simulating linux-64 on mac):

micromamba create -f environment.yml --dry-run --platform linux-64
