exports in package.jsons need to be updated to work with Metro.

Metro is the bundler for React Native. It has experimental support for the exports field in package.json, however I have had issues getting it to work with some of Evolu's packages. Things that need to change:

• Any conditional exports that use browser need to be default instead. Node recommends using default instead of browser here: https://nodejs.org/docs/latest-v19.x/api/packages.html#conditional-exports
  • Other alternative is to add a default conditional export with the same value as browser.
• Documentation needs to be updated to instruct users on how to enable experimental exports support in Metro:
  • If a user is using Expo, they need to follow these instructions to create their metro.config.js file.
  • Users will then need to add config.resolver.unstable_enablePackageExports = true; to their metro.config.js file.

This should fix errors users get where Metro cannot find Evolu's modules.

I will review it after the new sync and update docs. Thank you!
