serprog: Remove pico2 support for the time being

Many users report bugs, so I'm reverting lbmk back to only
supporting the rp2040 dongles for the time being. The
documentation will be updated to reflect this.

Pico2 support will be re-added at a later date, once more
testing has been done, and fixes made if necessary.
