wp_add_footnotes_revisions_to_post_meta()WP 6.3.0

This is a specific fix for the REST API. The REST API doesn't update the post and post meta in one go (through meta_input). While it does fix the wp_after_insert_post to be called correctly after updating meta, it does NOT fix hooks such as post_updated and save_post, which are normally also fired after post meta is updated in wp_insert_post(). Unfortunately, wp_save_post_revision is added to the post_updated which means the meta is not available at the time, so we have to add it afterwards through the "rest_after_insert_{$post_type}" action.
