Release Candidate 1 of EnergyPlus 25.1.0

Alright, there are several things to check here. The most user facing will be the new EPLaunch and VersionUpdater handling, but also the move to some more documentation on ReadTheDocs. With all the Python changes, I definitely need to exercise not only those apps and all the ways they can be accessed, but also confirming nothing broke with normal Python simulation workflows. I am also looking for the best ways to alert the users about the Python and doc changes.

There's really no reason this should fail since it just built happily on test #12 of the branch. But we'll see...
