Block added to revisions endpoint

[adambrgmn]

Hey! First, thanks for this awesome little library! Real easy to follow along in the code as well 👏
I'm just wondering if you know if it is possible to also add the blocks data to the revisions endpoints (/wp/v2/<post_type>/revisions/<id>)?

Btw while testing this out I found a way to do it. But it is not as good as the one used for "normal" post types:

\add_filter(
    'rest_prepare_revision',
    function (\WP_REST_Response $response, \WP_Post $post) {
        $has_blocks = \has_blocks($post);
        $blocks = [];
        if ($has_blocks) {
            $blocks = \WP_REST_Blocks\Data\get_blocks(
                $post->post_content,
                $post->ID
            );
        }

        $response->set_data(
            array_merge($response->get_data(), [
                'has_blocks' => $has_blocks,
                'blocks' => $blocks,
            ])
        );

        return $response;
    },
    10,
    2
);

This doesn't add the field to the api schema or anything. But for now this works for me.
