Disable buzzer electrically

[popy2k14]

In older versions we where supporting a buzzer as a fallback,
since newer esphome versions, local file playback has matured and working reasonable well.
If you used this feature (a buzzer is connected on your hardware to a pin), with this you can electrically disable it

Here is some things to add to the readme. I would not add this to the code.

switch:
  - platform: gpio
    pin: ${buzzer_pin}
    name: "buzzer pin - now unused"
    restore_mode: ALWAYS_OFF
