Hi! Thank you for this great ruby gem! I'm using this gem to parse doxygen xml in Ruby 3.2.2 but encounter an error.

/Users/myname/.rbenv/versions/3.2.2/lib/ruby/gems/3.2.0/gems/doxyparser-1.5.1/lib/nodes/compound.rb:32:in `parse': undefined method `exists?' for File:Class (NoMethodError)

      raise "No file found at this location: #{@xml_path} for node #{self.class.name} #{@name}" unless File.exists? @xml_path
                                                                                                           ^^^^^^^^
Did you mean?  exist?

I found it is because File.exists? is removed from Ruby 3.2. Could I create a PR to fix it?

I added a gem named file_exists and it works! Just leave this comment to help others encounter the same error.
