Description: Make NotRubyParser compatible with prism 0.19.0 in Debian/Ubuntu
 Conditionalize the definition of NotRubyParser so it falls back to the
 classic RubyParser (from the ruby_parser gem) when Prism::Translation::RubyParser
 is not available (as in prism 0.19.0 shipped with ruby3.3). On newer Prism
 versions (>= 0.23) it uses the upstream-intended translation layer.
