boards/rpi-pico: update openocd.cfg file

[dylad]

Contribution description

This PR fixes the use of openOCD to flash a rpi-pico board.
Currently on master, trying to flash this board with openOCD (v12) and a CMSIS-DAP probe fails.
with this PR, it now works as expected (even debugging)
Moreover, the configuration file used by RIOT is now deprecated on openOCD v12 so changes it while we're at it.

master:
