Fix dead link for Modern Perl book

[waterkip]

Closes: #5523

Given that this book is not available online and seems quite old, maybe it's better to just let test writers select their own Perl resources instead of directing them to potentially outdated info? WDYT @stapelberg

Hmm, not sure. I think the book is still valuable, though building it from source is not something that people will do, I think. Could we build it from source and distribute a static PDF version of it, or does the license not permit that?

The book might be useful indeed but instructing contributors on how to learn a language is not really typical for an open source project. Besides, it might be discouraging people rather than helping them; it creates the impression that one has to read a full book before actually contributing to i3 ("Please read the following documents before working on tests"). I believe that for the scope of what we are doing, great knowledge of perl is not needed to contribute to i3. I've personally never read the book.

Okay. I have saved a copy of the PDF, you can refer to it as https://i3wm.org/downloads/modern_perl_a4.pdf

Yes, but Perl isn’t really a typical language for an open source project either (these days). I’m open to changing the wording to seem less daunting, but I do think it is good to provide a few pointers regarding known-good resources to get into Perl for people who prefer that approach. Of course, everyone is free to disregard the advice and just jump into the code :)

I updated the link in the PR.

Perl is a great language :)
