[RF] Proposal fix for issue #2139 + Extra documentation (#2157)

* Refactor announceDeviceTrigger function to improve parameter handling and documentation for optional device information
Fix null pointer references in RFtoMQTTdiscovery and update logging levels for RF signal handling
Refactor RF to MQTT discovery functions for improved clarity and parameter handling

* Update documentation for RF auto discovery and MQTT integration, correcting terminology and enhancing clarity

* Refactor enableRFReceive function to accept parameters for frequency and GPIOs, enhancing flexibility
