• test/disable-request-logging.test.js was failing prior to any new work. This test made to pass by changing t.plan(10) to t.plan(9). I do not know the larger impact of this change.
• overriding net.connect to force a timeout was taken from undici's test/connect-timeout.js.
• a new ConnectTimeoutError error object was created to handle this error.
• 500 status error was used because this is what undici uses.
• I could not figure out how to get the FakeTimers working for this test. There is a 50ms connectTimeout that waits in real time.
• This is my first contribution to this project and I am not familiar with this codebase so please triple check my work.

I'm just here for the cat. Oh, and the CI is failing 🙃
