[Tails-dev] [review'n'merge:1.3.1] bugfix/8991-polish-Whispe…

Hi,

this branch makes the sudo config and sudo-run tails-debugging-info
script used by WhisperBack a bit more defensive. And while I was at
it, it fixes a bunch of typos and grammar mistakes in the WhisperBack
configuration file, and s/amnesia/Tails/ in there.

Cheers,
