Deep linking instruction may need an update

I'm trying to implement deep linking in my app but there are some inconsistencies between React Navigation's doc, React Native's and Android's which makes me feel confusing. For example, in https://reactnavigation.org/docs/en/deep-linking.html#android-1 it's talking about "Set launchMode of MainActivity to singleTask" with a link to the respective Android doc page, however there's no mentioning about this over there and the XML code snippet looks quite different; same is also true for the iOS section, the snippet given in https://reactnavigation.org/docs/en/deep-linking.html#ios-1 was outdated according to https://facebook.github.io/react-native/docs/linking

Someone in the know may wanna look into this and update the docs.

Confronta la pagina sul deep linking di React Navigation con la documentazione collegata di React Native, Android e iOS, concentrandoti sugli snippet di codice relativi a launchMode e alla piattaforma menzionati nell’issue. Aggiorna le istruzioni in modo che corrispondano alle indicazioni attuali della piattaforma, quindi verifica che la documentazione sul deep linking sia coerente tra le varie sezioni.
