Update example-navigation.md

[vanGalilea]

Hi :wave: My name is Steve Galili, big fan of the library I've discovered lately after participating in a workshop given by Kent. I've added an extra navigation example that suits react-navigation v5.

It will be great if you could update this in your docs. I have more examples up my sleeve see my example repo https://github.com/vanGalilea/react-native-testing

I would be happy to contribute more to this repo, if you need more help.
