Lint/Debugger does not catch require "debug/start"

[odinhb]

There is a feature in the debug gem where you can require the gem and enter the debugger in a single statement. I don't think other debuggers have this so it is being missed by the Lint/Debugger cop.

The feature allows the following statements to start a debugger:

require 'debug/start' # Same as rdbg.
require 'debug/open' # Same as rdbg --open.
require 'debug/open_nonstop' # Same as rdbg --open --nonstop.

I don't think we want any of these to accidentally make it to production.

Expected behavior

Lint/Debugger should complain about this code, since it is a debugger breakpoint the same way as putting debugger in your code is:

def a_method
  x = 2 + 2

  require "debug/start"

  x * 2
end

Actual behavior

1 file inspected, no offenses detected

Steps to reproduce the problem

Put require "debug/start" in your code. $ rubocop

Attempted workaround

This has no effect:

Lint/Debugger:
  DebuggerMethods:
    requires:
      "require \"debug/start\""

I would assume this cop configuration does not support checking for the specific argument to require. Maybe I'm missing something?

debug/open_nonstop should be excluded from this list as it's NOT a breakpoint require. It simply activates the debugger in remote mode but doesn't stop the program. And its main usage is to be put behind a flag to enable convenient debugger-editor integration. Here's an example from the Ruby LSP. And according to this issue: rails/rails#51225, some Rails projects also use it the same way. So please exclude it from the current list. cc @Earlopain

@st0012 Thank you for the feedback. I've opened #12845 to solve it.
