[build] Fixup maven publishing (#8753)

This primarily fixes up the bazel publishing to match the gradle
publishing again, as some new libraries were added but not hooked up to
the maven publishing.

During the process, I noticed that the 3rd party libraries (googletest,
catch2, and imgui_suite) were still getting published on the old
`edu.wpi` namespace. I tried to clean up all the other references to
that that I could. Note: opencv and libssh are handled outside
`allwpilib` so they need to be updated separately.
