Add racc dependency because it will be bundled

Ruby 3.3.0 is going to start warning for racc not being specififed as a
dependency, and Ruby 3.4.0 will raise if it is not specified.

This commit prevents those issues by adding racc to the Action Pack
gemspec, since `racc/parser` is a runtime dependency of the Journey
parser.
