Updates for raylib 5.5

[ricardobeat]

This gets examples working again, but I might have missed something.

It seems like the Ruby code is supposed to be auto-generated based on the official raylib_api.json file?

• https://github.com/wilsonsilva/raylib-ruby/blob/main/docs/architecture-decisions/0008-writing-code-vs-using-generators-vs-using-ai.md

• raylib-ruby/Rakefile

  Lines 14 to 16 in 7581c08

  	# If you're developing the generator, uncomment these lines and point it to your local copy of the generator
  	# require_relative "../raylib-generator/lib/raylib/generator"
  	# require_relative "../raylib-generator/lib/raylib/generator/tasks"

• raylib-ruby/Gemfile

  Lines 8 to 9 in 7581c08

  	# If you're developing the generator, uncomment this line and point it to your local copy of the generator
  	# gem "raylib-generator", path: "/Users/wilson/projects/rb/raylib-generator"

But I cannot find the code for raylib-generator. Please, @wilsonsilva, make it available somehow 🙏
