Readline test fixes

[heimskr]

What does this PR do?

Adds new readline tests from Node.js and changes to Bun that cause the tests to pass.

• Documentation or TypeScript types
• Code changes

How did you verify your code works?

• I included a test for the new code, or existing tests cover it
• I ran my tests locally and they pass (bun-debug test test-file-name.test)
