Show that localization at minimal primes results in rings with only a single prime ideal, implying that every non-unit element is nilpotent.

It wouldn't take much effort to show that the prime spectrum of these rings is a single point but I'm not sure where this would fit exactly

I agree that this should be added, probably in Mathlib.AlgebraicGeometry.PrimeSpectrum.Basic (where, for instances, there are results like PrimeSpectrum.t1Space_iff_isField )

Done. I think the Uniqueness result should be enough for the moment

Here is a slight refactor that introduces IsLocalization.AtPrime.orderIsoOfPrime and IsLocalization.AtPrime.prime_unique_of_minimal. Feel free to merge if it looks good.

Apart from @alreadydone 's comment, the whole PR now LGTM.

If you add docs to the def to make it compile, I'll do so, sure!

I've now added a docstring, but this is something you could have done :)
