Support for Reusable blocks

[williamjulianvicary]

As a proof of concept, I think this is reasonably trivial, the below added here ContentBlocksResolver.php:56 and the reusable blocks seem to resolve as expected. I've not done extensive testing yet, but the GQL response looks good and replacing a few components in active pages seems to work as anticipated. Given it's just replacing the core/block with the content of the rendered reusable block(s), it should be good to go with something as trivial as this?

Let me know if you'd like a PR and I'll wrap up some tests and get that added

        // Resolve reusable blocks
        $new_parsed_blocks = [];
        foreach ($parsed_blocks as $block) {
            if ($block['blockName'] === 'core/block' && $block['attrs']['ref']) {
                $reusable_blocks = parse_blocks( get_post( $block['attrs']['ref'] )->post_content );
                if (!empty($reusable_blocks)) {
                    array_push($new_parsed_blocks, ...$reusable_blocks);
                }
            } else {
                $new_parsed_blocks[] = $block;
            }
        }

        $parsed_blocks = $new_parsed_blocks;
