Bug#1000832: Mention how to turn off GRUB_DISABLE_OS_PROBER warnings

[積丹尼 Dan Jacobson]

Package: grub-pc
Version: 2.06-2

We see two warnings:

Setting up linux-image-5.15.0-2-amd64 (5.15.5-1) ...
...
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.

Setting up grub-pc (2.06-2) ...
...
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.

We look at
(info "(grub) Simple configuration")
and read about GRUB_DISABLE_OS_PROBER.

But nowhere is it mentioned how to turn off those two warnings.

No, we don't want to turn on the prober. We just want to turn off the warnings.
