Description

The [doc](https://www.esphome.io/components/mqtt.html) has no arduino TLS/SSL example.
The `certificate_authority: ` option is **used with the esp-idf framework** ONLY.
Can anyone give me some yaml examples?

Research direction

Start with the linked MQTT documentation and its framework-specific TLS notes; verify whether the Arduino framework supports the requested connection and which configuration fields apply. Document a working YAML example or state the limitation clearly, with the finished documentation covering the Arduino case.
