Draft: fix: conditionally import react navigation

[tjaniczek]

Fixes #3952

Summary

Unfortunately Webpack won't allows us to import missing export via ES6. Dynamic imports are a no-go as well. They're async and since we want to import hook we end up with Promise<useLinkTools>. This would break rules of hooks since we'd have a conditional hook rendered (before and after async import).

The only solution I found is to import the whole package as CommonJS. This won't break the rules since it's sync. It will import once and then only one hook will be returned.

Test plan

Example app does not throw an error anymore on either v6 or v7

Using CommonJS also isn't ideal because bundlers do not do tree shaking

The mobile version of example app from this branch is ready! You can see it here.
