Resolve incorrect wiring instructions (#984)

As identified in this forum post (
https://community.openmqttgateway.com/t/rtl-433-esp32-bme280-but-what-ra
dio/1563) , the default builds have incorrect connections for the
RTL_433 module.  This fixes the default build configuration and
crispness the documentation.

 To use the CC1101 module, `ZradioCC1101` must be uncomment in the `User_config.h` or added to the `build_flags`.

( Please note that with OMG we are recommending CC1101 GDO2 to be connected to ESP32 D27 and GDO0 to be connected to D12, this is different than the LSatan diagram. This is due to the ESP32 using D2 as part of the boot process. )
