Update Expo.md

Hi 👋

One thing I'd like to update and make it future proof for Expo specific projects is to update the installation command from expo install... to npx expo install.... Since the latter referees to the new Expo CLI, which doesn't require any global package installation. For expo install, people will need to install the deprecated global cli (and we are not recommending that).

Also, update docs related links.

Thank you!
