* Update feature_advanced_keycodes.md

Probably a better way to word it, but I've solved this issue on reddit several times, had to solve this for friends, ect. It's something worth being in the docs as it's a common issue, and not always intuitive. I have offered this change as I was told by several people "It was never mentioned in the docs".

* Update feature_advanced_keycodes.md

Clear up what was meant to be said.

Chibios_test/stm32_f072_onekey: Add support for reset to bootloader (#4238)

* Add support for reset to bootloader

Chibios_test/STM32_F072_ONEKEY wouldn't reset to bootloader on a
