fix: For Ruby 3.3 compatibility, specify racc dependency in gemspec

[faisal]

This PR adds racc to the gemspec, because Ruby 3.3 changes mean that without it we get:

~/test (+main) $ cat Gemfile 
# frozen_string_literal: true

source "https://rubygems.org"
~/test (+main) $ license_finder
<internal:/opt/homebrew/Cellar/ruby/3.3.0/lib/ruby/3.3.0/rubygems/core_ext/kernel_require.rb>:127:in `require': cannot load such file -- racc/parser.rb (LoadError)

I think this should actually be fixed in tomlrb: fbernier/tomlrb#50

[itchyny]

@benlangfeld I'm confused by the tomlrb PR was merged without any fixes about the dependencies.

The test suite passes on ruby 3.3.

[xtreme-shane-lattanzio]

@faisal Ill add 3.3.x support to the pipeline. There are a few things missing from this so Ill make sure pipelines are added and they pass

[itchyny]

@xtreme-shane-lattanzio Thanks for maintenance, would you release a new version for Ruby 3.3 support?
