The project moved to meshcore-dev/meshcore, but two links still pointed at
ripplebiz/MeshCore: the GitHub Issues link in README and the git clone in the
FAQ build instructions.
Also fixes the FAQ build recipe:
- `pio run -e RAK_4631_Repeater` does not exist; the env is spelled
RAK_4631_repeater (variants/rak4631/platformio.ini:40).
- LORA_FREQ was given as 867.5; the default in [arduino_base] is 869.618
(platformio.ini:29). Reworded to point at the flag rather than a value that
drifts with the default preset.
- Renamed the venv so it no longer collides with the cloned directory name.
And one more env-name casing slip in the Raspberry Pi flashing instructions:
`Heltec_V3_companion_radio_ble` should be `Heltec_v3_...`. Release artifacts are
named directly from the env name (build.sh:147), and the two neighbouring
examples in the same block already use the lowercase spelling.
This is a key difference compared to other systems and I see people
asking this a lot. It is mentioned in the FAQ but let's make it more
prominent in the README.
Added small section under RAK compatibility for info on how to convert hex to uf2, with link to Microsoft GitHub uf2conv python script. Cleaned up how links display in that section.
