Describe the Bug

We want to use the apt_key resource type using source and we want to provide proxy options.

Expected Behavior

Proxy is used

Environment

• Version PE 2021.7.1 - Puppet 7
• Platform Ubuntu 20

Additional Context

see https://github.com/puppetlabs/puppetlabs-apt/blob/main/lib/puppet/provider/apt_key/apt_key.rb#L194
This if statement matches only if source and content are both nil.
If either one is set the options will not be added to the command.
