Concurrency chapter - example of goroutine loop variables is no longer applicable as of go version 1.22

tldr - This behaviour is something that has been addressed in the latest go release.

I am currently reading this book (excellent btw), and am coding along until I get to the '...and we're back' section of the concurrency chapter.

I ran this example and my tests pass just fine.

I then set out to investigate why, as this should fail according to the chapter, and this video cleared things up for me -

Good spot! Do you fancy making a PR?

I'll give it a shot, sure! I'll try and tackle it this weekend.

I took some minutes and added a PR for this.
