docs: Update Expo installation instructions (#2991)

## Description

<!--
Description and motivation for this PR.

Include 'Fixes #<number>' if this is fixing some issue.

Going through the Expo section on the Installation page, I found installation instructions were outdated. The managed term is deprecated since only Expo Go and development builds are currently reliable terminologies when it comes to starting a new Expo project. To reflect this, this PR makes the following changes:
- Remove use of managed as a term and section heading
- Add link to H2 heading for Expo
- Change `expo install ...` command to `npx expo install ...` since `expo-cli` is deprecated and now local Expo CLI is used inside an Expo project to install a new library when running `expo install`.
- Update Expo link to expo.dev since expo.io is no longer a working domain
- Update Bare section about initializing a new project with `create-expo-app` whose default template now comes with `react-native-gesture-handler` library installed. The bare template which has been updated since `expo-cli` was deprecated has now become `bare-minimum` and doesn't include this library. I've also added a link to the Create a project page in Expo docs.
- Fix React Native link in the sub section heading to use `https` protocol.
- Remove `expo-cli` reference and link.
