File metadata not passed from docs page template to Video component

[arcticicestudio]

The Video component maps the video file metadata received from props.sources (array of objects) to the <source> HTML tag, but for docs pages the MDX DocsPage component only passed down the publicUrl metadata field resulting in a array of strings. This causes the Video component failing to load the video file(s) for MDX docs pages.
To fix the invalid mapping the DocsPage component should pass down the whole video file metadata object instead of only the publicUrl (string) field.
