[Docs] Add Alex as a recommendation to the "Writing" guidelines

[j-m]

I recently came across a great tool called Alex which analyses your text for phrasing that others may find insensitive or inconsiderate.

I didn't know such tools existed, so it'd be awesome if we could start a collection of recommendations in the guidelines (here?). Of course I totally understand if not, but I thought I'd ask anyway :)

Hi @j-m,
Thanks for suggesting Alex and the idea for a collection of recommendations. I didn't know about this tool and it seems very interesting.

@gchaps is working on some updates in our Writing guidelines so I let her know about this tool and your idea for the collection.

I'm also converting this issue into a discussion so we can all contribute with ideas. 🙂

Thanks for the tip. We'll keep it in mind as we update our writing guidelines.
