Update configuring-links.md

[matteo-hertel]

Overview

I have a main navigator with a bunch of screens, I wanted a deep link to one of those screens to go back to the initial route and I couldn't get it to work, after diving into the source code I found that a top-level initialRouteName can be passed and that solved my problem, the docs are a bit ambiguous so this PR hopefully will save the next person a few hours of debugging

Thank you so much for making and maintaining react-navigation, it's amazing and delightful working with it!

TODO

• [x] update all the different docs version
