hdd temp has been marked as obsolete

[Otto-G]

Need to replace hddtemp with the drivetemp kernel module

hddtemp (0.3-beta15-54) unstable; urgency=medium

hddtemp has been dead upstream for many years and is therefore in a minimal
maintenance mode. It will be shipped in the Debian Bullseye release, but
will not be present in the Debian Bookworm release.

Nowadays the 'drivetemp' kernel module is a better alternative. It uses the
Linux Hardware Monitoring kernel API (hwmon), so the temperature is returned
the same way and using the same tools as other sensors.

Loading this module is as easy as creating a file in the /etc/modules-load.d
directory:

echo drivetemp > /etc/modules-load.d/drivetemp.conf
