register as MDAKit

[orbeckst]

The MDAKit registry https://mdakits.mdanalysis.org/ is now in beta and MDSAPT would make for an excellent "official" MDAKit, given that it was one of the very first inofficial ones. MDSAPT is already a prototypical MDAKit so it should be easy enough to register it.

We are working on creating a tutorial and other content to guide users in addition to the currently terse Adding an MDAkit to the registry. We are also planning an online mini-workshop for around the end of April/beginning of May for early adopters and developers, which we will advertise soon. In our Discord we have a #mdakits channel where we're more than happy to help with any questions.

@orbeckst we started the process of creating a conda-forge deployment (issue #45) and fixed the install issue related to pydantic updates (it also had some transitive dependency issue with a psi4 dependency). Once we get that done I'll finish registering it as an MDAKit.
