Import mediaUpload from @wordpress/editor (#14651)

With the components moving from the @wordpress/editor package to
@wordpress/block-editor the import statements were updated. However, the
mediaUpload function didn't move packages and this broke part of some of
the meda block's upload mechanisms.

This change swaps back to importing mediaUpload from @wordpress/editor
