Cannot remove all options.

[traylenator]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7
• Ruby: 2.7
• Distribution: RHEL9
• Module version: 4.0.0

How to reproduce (e.g Puppet code you use)

pam{'Add pam_xdg_runtime_dir':
  ensure    => $_state_ensure,
  service   => 'sshd',
  type      => 'session',                                                  
  control   => 'optional',
  module    => 'pam_xdg_runtime_dir.so',
  position  => 'before *[type="session" and module="pam_krb5_cc_move.so"]',
  arguments  =>['debug'],
  require   => Pam['Add pam_krb5_cc_move'],
}

This correctly adds

session    optional      pam_xdg_runtime_dir.so debug

After re-running puppet with arguments as [] or undef the existing arguments are not removed.

What are you seeing

Seems to be not possible to delete all existing arguments.

What behaviour did you expect instead

That [] or undef would delete all of the arguments.
