[Bug 1973432] [NEW] os-prober skip message is misleading

[Henning Sprang]

Public bug reported:

os-prober appears not toe be executed when the string "osprober" is not
found in /boot/grub/grub.cfg.

While I am still on my way to understand what that means and if this is
probably and error, because the string to search for should be "os-
prober", one thing is clearly less than ideal:

The information message tells the use to check the
"GRUB_DISABLE_OS_PROBER" meaning in grub documentation.

But the reason why ths steps is skipped in that code line, is because a
greo command.

The outout should tell the user so!

(ubuntu-bug uploaded my slightly modified version that changes the
behaviour, this description refers to the unmodified version!)
