WKWebViewConfiguration: Enabling Media Playback Features

The code provided creates a WKWebViewConfiguration object called 'config'.

The first line of code sets the mediaTypesRequiringUserActionForPlayback property of the 'config' object to .all, meaning that user interaction is required for all media playback within the web view.

The second line of code sets the allowsInlineMediaPlayback property of the 'config' object to true, enabling media playback to occur inline within the web view instead of launching a separate fullscreen player.

The third line of code sets the allowsAirPlayForMediaPlayback property of the 'config' object to true, enabling media playback to be streamed to an AirPlay-enabled device.

The fourth line of code sets the allowsPictureInPictureMediaPlayback property of the 'config' object to true, allowing media playback to be displayed in a picture-in-picture mode on devices that support it.
