Use forked Adafruit nRF52 framework with LittleFS v1.7.2 and Bluefruit fix

Switch from registry package to weebl2000/Adafruit_nRF52_Arduino fork
(tag 1.10700.1) which includes:
- LittleFS v1.6 → v1.7.2: fixes filesystem corruption on renames
- Bluefruit BLE semaphore restore on disconnect: fixes device lockup

The build-time patch_bluefruit.py script is no longer needed as the fix
is now in the framework source.
