Twenty Twenty-One: Enable Dark Mode in the block editor iframe.

This changeset replaces `add_action( 'enqueue_block_editor_assets' )`, with `add_action( 'enqueue_block_assets' )`, in class `Twenty_Twenty_One_Dark_Mode` and class 
`Twenty_Twenty_One_Custom_Colors`. This fixes an issue when activating dark mode in Twenty Twenty-One, where dark mode was not enabled in the block editor.

Fixes #58835.
