fix(app,learn,meditate): a device without speech recognition says so, and how to get one

Browse source 
On GrapheneOS, which installs no recogniser, the microphone did nothing
and stayed listening: speech_to_text's initialize throws a
PlatformException (recognizerNotAvailable) there rather than answering
false, and DeviceSpeechInput let it through. A listen now answers how it
went (SpeechStart: listening, noRecognizer, unavailable) and never
throws; Learn's field and Meditate's dream say that no speech
recognition is installed and name two to install (FUTO Voice Input,
Google's speech services), in halkyon_app's texts. It also passes
androidNoBluetooth, as the apps declare no Bluetooth permission the
plugin would otherwise ask for.

Whats-New: Where the device has no speech recognition, the microphone says so and how to get one.
Whats-New-De: Wo das Gerät keine Spracherkennung hat, sagt das Mikrofon das und wie du eine bekommst.
