[Feature] provide FW update available of add-on via MQTT

[thyzzv]

Describe the feature
Would it be possible to provide the 'Firmware update available' of the add-on itself via MQTT?
That way we wouldn't have to login to the add-on itself to check for newer versions (or follow the GoT toic very precisely)

Expected behaviour
Provide an 'fw_update_available' boolean on the mqtt status topic for the add-on.
or a 'available firmware version' field

certainly possible. The json file could be parsed from github lets say once a day. Only downside is that connecting to github requires https client support in the firmware which is quite costly firmware size (adds about 180kb).
Maybe some other solution is possible...

Ah I had not noticed that the firmware check is done locally in the browser. Not on the device
180kb is indeed a lot.
