On Ruby 3.3 Readline was finally replaced by reline.
Currently pry kinda works, but has some edge cases like #2297 that were working on previous versions with Readline.
We can go back to older readline via installing `readline-ext'. ref As the default that come with ruby is Reline, we need some kind of support here.
This PR attempts to add reline support, multiline editing, and so on. Making Pry compatible.
