[expo-video] Add expo-video docs page (#27854)

# Why

Expo-video is missing a docs page.

ENG-11349

# How

Renamed the `video.mdx` to `video-av.mdx` and assigned `video.mdx` as
`expo-video` docs page. We should consider doing this the other way
around (adding a suffix to `expo-video` file). Current way might create
issues with linking to the docs, eg. if someone wants to redirect people
to the latest `expo-av` video docs so they would link to
`https://docs.expo.dev/versions/latest/sdk/video/`, but the users will
be redirected to `expo-video` docs after SDK 51. I kept it this way in
case we believe people should be redirected to `expo-video` anyways. Let
me know what you think about it :)

Created a simple example for `expo-video` (similar to the `expo-av`
example), which showcases how to use player properties and events.

+The `Video` component from `expo-av` displays a video inline with the other UI elements in your app.

+Much of Video and Audio have common APIs that are documented in [AV documentation](av.mdx). This page covers video-specific props and APIs. We encourage you to skim through this document to get basic video working, and then move on to [AV documentation](av.mdx) for more advanced functionality. The audio experience of video (such as whether to interrupt music already playing in another app, or whether to play sound while the phone is on silent mode) can be customized using the [Audio API](audio.mdx).
