ST Microelectronics Nucleo64-G431RB onekey

Supported Hardware: https://www.st.com/en/evaluation-tools/nucleo-g431rb.html

To trigger keypress, short together pins A9 and A10.

The usual USB connection to ST-Link will not work for QMK -- pins A11 and A12 need to be connected to D- and D+ respectively.
