New board/Waveshare RP2040-GEEK:Product ID update.

Waveshare support got back to me and supplied the Product ID for this
device. Apparently they renamed the device since applying for the
Product ID. The original name was RP2040-HACK. I'm assuming the
MICROPY_HW_BOARD_NAME doesn't have to match the registered name so it
can stay as is with the correct (current) name.
