Compatibility in ruby >=3.2 ?

[Jaco-Pretorius]

I am having issues with running derailed against a Rails app with Ruby 3.2.2. The issue is rather obscure, but I'll put the stacktrace here

I suspect this is because the dead_end gem - which is the syntax_suggest repo - has been integrated with Ruby 3.2. At the very least it's not clear to me what is expected to happen if you include that gem while running Ruby 3.2 or later. There is an issue against the syntax_suggest repo which seems to indicate that you no longer need to include the gem but it doesn't say what will happen when you do. The stacktrace above does point to some of the require_relative overrides going on in that gem.

This would only ever fire if you’ve got a syntax error or are trying to load a file that doesn’t exist.

if someone wants to remove dead-end or upgrade it to syntax_suggest I would accept the change.

(possibly) addresssed by #228 which replaces dead_end with syntax_suggest which is the renamed library
