Fix AbortController being reused in multiple fetch requests in some o…

[marcindz88]

Description

The AbortController examples include code that reused the same AbortController instance across multiple fetch calls, which causes them to be instantly cancelled.

Motivation

The documentation should be updated to help developers understand that an AbortController instance cannot be reused.

Thank you for the fix, @marcindz88 ! The code looks good to me but the description needs tweaking a bit, especially the paragraph starting "We first create a controller...", because we don't, any more :).

@wbamberg Do you think we could leave the example on the AbortController page and include only a link in the methods and constructor to not repeat this or is is a common practice here to include it on all pages for easier accessibility ?

Yes, I think this is a good idea. I'm not really a fan of this style where we duplicate examples, it's such a maintenance burden.
