(PA-5016) Bump CFPropertyList to 3.0.6 for Ruby 3.2

CFPropertyList versions < 3.0.6 have a File.exists? call but File.exists? was
deprecated and removed in Ruby 3.2. Currently, this blocks adding macOS 11 & 12
to puppet-agent#main, which uses Ruby 3.2, as a TEST_TARGET. This commit bumps
CFPropertyList to 3.0.6 whenever the Ruby version is >= 3.2.
