apt::mark with setting auto is not idempotent

[FrankVanDamme]

Describe the Bug

apt::mark with setting "auto" will execute every run

apt::mark { 'lib1':
setting => auto,
}

The behaviour is quite similar to #1166.

Expected Behavior

To mark a package as automatic if it is installed and not marked as automatic.

Environment

• puppetlabs-apt v10.0.0;
• Debian 11 or 12

Additional Context

The main issue I believe is that the module tries to mark packages as auto that are not installed. What happens in that case:

• the package will not show up in the output of "apt-mark showauto", since non-installed packages can't be marked
• the onlyif setting wil always return true: "dpkg -l " will show that the package is uninstalled, but that doesn't mean it returns non-zero exit status. It only does so if the package doesn't exist in the sources.

Suggest changing the check to something like:

$onlyif_cmd = ["/usr/bin/dpkg -l $title | grep '^ii '" ]
