Note: I’m happy to make a pull request to fix this, I just wanted to log it first to ensure there’s interest.

React’s [synthetic media events](https://reactjs.org/docs/events.html#media-events) contain several [existing media events](https://html.spec.whatwg.org/multipage/media.html#mediaevents), for instance `onLoadedMetadata` and `onVolumeChange`. But there is no `onResize` handler.

[`resize` is a standard media event](https://html.spec.whatwg.org/multipage/media.html#event-media-resize) that triggers when one or both of the `videoWidth` and `videoHeight` attributes have just been updated. It’s useful for responding to resolution changes in video players.

React version: 17.0.2 (latest release as of initial issue report)

## Steps To Reproduce

1. Create a `<video>` element with an `onResize` prop.
2. Check the console for the following warning:

```
 Warning: Unknown event handler property `onResize`. It will be ignored.
```

Link to code example: https://codesandbox.io/s/musing-snowflake-zb0qh?file=/src/App.js

## The current behavior

`onResize` handlers are ignored on `<video>` elements.

## The expected behavior

`onResize` handlers are valid on `<video>` elements.
