Find all examples of PIR embedded in POD documentation anywhere in the repository, and wrap them in PIR target blocks like this:

=begin PIR
     
 .sub main :main
    'MySub'("name" => "Bob", "age" => 42)    # Same!
 .end
  
=end PIR

For bonus points, run t/examples/pod.t after you do this and fix any errors this finds in the sample PIR.

For now, only do this with PIR examples that contain complete subs and are expected to work.
