docs: add util-linux-script package for Fedora 42+

Fedora 42 split the script utility from util-linux into a separate
util-linux-script package. This change adds conditional installation
of util-linux-script for Fedora 42 and later versions.
https://src.fedoraproject.org/rpms/util-linux/c/5a2471d6e5b0055cb607b30dc2e9613b312ffb74?branch=rawhide

The package is added conditionally using rpm macro evaluation to
maintain compatibility with older Fedora versions where script was
included in the base util-linux package.

Note that different distributions handle this differently - for example,
Debian provides the script utility in a separate bsdutils package
rather than in util-linux.
