fedora-intune: don't repeat the version in the reported OS version

libhimmelblau reports "PRETTY_NAME VERSION_ID" as the OS version, and
Fedora's PRETTY_NAME already contains the version, so Entra showed
"Fedora Linux 44.20261020.0 (Forty Four) 44.20261020.0". In the
os-release the Himmelblau daemons see, set PRETTY_NAME to NAME, giving
"Fedora Linux 44.20261020.0". Nothing else in Himmelblau reads
PRETTY_NAME.
