audio/praat: update to 6.4.65, latest upstream
Release notes, as always, at
https://www.fon.hum.uva.nl/praat/manual/What_s_new_.html
There has been a lot of changes, including possibly AI-speech-detection.
Perhaps that means ML. I have not tested this feature.
JACK was added upstream as a dependency, which
I have removed again in FreeBSD porting.
