Twenty Twenty-One: Prevent notice thrown in twenty_twenty_one_get_attachment_image_attributes().

Browse Source 
Calling `twenty_twenty_one_get_attachment_image_attributes()` was causing an `Undefined index: width|height` notice to be thrown when the result from `wp_get_attachment_metadata()` does not set any value to `$meta`. This change adds an `isset()` check to prevent it.

Props wetah, hasanuzzamanshamim.
Fixes #54464.
