[ruby/prism] Follow RuboCop's parser engine support

With the introduction of Prism::Translation::Parser to RuboCop (RuboCop AST),
the number of arguments for RuboCop::AST::ProcessedSource#parser_class internal API will be changed:
https://github.com/rubocop/rubocop-ast/pull/277

Before¶

As a result, the following error will occur starting from the next release of RuboCop AST (< 1.30.0) :

$ bundle exec ruby -rrubocop/ast -rprism -rprism/translation/parser/rubocop -ve \
"p RuboCop::AST::ProcessedSource.new('42', 80_82_73_83_77.33).ast"
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
/Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser/rubocop.rb:25:in `parser_class':
wrong number of arguments (given 2, expected 1) (ArgumentError)
        from /Users/koic/src/github.com/rubocop/rubocop-ast/lib/rubocop/ast/processed_source.rb:309:in `create_parser'
        from /Users/koic/src/github.com/rubocop/rubocop-ast/lib/rubocop/ast/processed_source.rb:219:in `parse'

        from -e:1:in `new'
        from -e:1:in `<main>'

After¶

This PR prevents the above error by updating the monkey patch to support the new argument:

$ bundle exec ruby -rrubocop/ast -rprism -rprism/translation/parser/rubocop -ve \
"p RuboCop::AST::ProcessedSource.new('42', 80_82_73_83_77.33).ast"
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
s(:int, 42)

Moreover, to ensure compatibility with the existing RuboCop AST, conditional logic
has been implemented to maintain backward compatibility.
