Adds NSSpeechRecognitionUsageDescription to Info.plist.in

Without this, we cannot launch processes that use macOS's
speech recognition APIs.
With NSSpeechRecognitionUsageDescription in place, macOS displays the
dialog asking the user to grant permission and allows the speech APIs
to be used from the process.
* nextstep/templates/Info.plist.in: Add
NSSpeechRecognitionUsageDescription key.  (Bug#72827)

* etc/NEWS: Announce the change.
