Add PPLib offline installer download

Is your feature request related to a problem? Please describe.
Not an active problem, but one that could exist. At competitions my team and several others like to have an offline installer of all of the libraries they use in case if something goes wrong with gradle cache, however path planner doesn't have an offline installer available.

Offer an offline installer for PPlib

The artifacts for release builds are available from the workflow here. These can be placed in your gradle cache manually.

I likely won't be doing an actual installer, since its just a lot more to maintain when very few will likely ever use it.

How would I manually add these to the gradle cache though? There doesn't seem to be a defined location for them

C:\Users\Public\wpilib\2024\maven

Just drop the com folder from the build artifact in there.

The problem with this approach is that the artifacts do expire. I will admit, I'm in a bit of an odd situation where I had to reimage my school laptop mid way through the year, and because github pages is blocked I can't access the online artifacts. Luckily, I do know how to get the artifacts from either the Github pages repo or by building manually, but it'd be nice if there was at least a note in the docs that explained the process
