Bump dependencies, add Ruby 3.3 to test matrix

[RSO]

httparty 0.21.0 is throwing deprecation warnings in Rails on ruby 3.3:

~/.rbenv/versions/3.3.2/lib/ruby/gems/3.3.0/gems/bootsnap-1.18.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:30: warning: ~/.rbenv/versions/3.3.2/lib/ruby/3.3.0/csv.rb was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add csv to your Gemfile or gemspec. Also contact author of httparty-0.21.0 to add csv into its gemspec.

This PR adds testing for Ruby 3.3, and changes the httparty dependency to ~> 0.22.0.

Thanks for the submission!

Looks like the side effect of the the other bundle updates are linting errors :/

Let me see if I can make it so that this only upgrade httparty!

This should now be ready for review/merge again!
