Modifying existing resources crashes with Puppet 7

[supertassu]

Description of problem

• What did you do? Made a change to an existing resource in a manifest, and used octocatalog-diff to compile the changes for a host where that manifest is applied.
• What happened? I get an error, /usr/lib/ruby/vendor_ruby/octocatalog-diff/catalog-diff/filter/compilation_dir.rb:72:in new': tried to create Proc object without a block (ArgumentError)`
• What did you expect to happen? I see the difference in the catalog
• How can someone reproduce the problem?

Platform and version information

• Your OS: Debian GNU/Linux, running the testing release
• Your Ruby version: ruby 3.0.4p208 (2022-04-12 revision 3fa771dded) [x86_64-linux-gnu]
• Your version of Puppet: 7.20.0, the open source version as packaged in Debian
• Your version of octocatalog-diff: octocatalog-diff 2.1.0-1, again installed from the packages in Debian repositories

Do the tests pass from a clean checkout?

No,

This seems to be an issue with a newer Ruby version, not with a newer Puppet version. The following patch seems to fix it, but I'm not very familiar with Ruby and therefore not sure if it's the correct or proper fix:

I can confirm the problem, also seeing it with ruby 3.1.2p20 (as present in Debian/bookworm) and puppet-agent v7.23.0-1bullseye (from puppetlabs upstream).

Thanks @supertassu for providing a patch, this also works for me!
