When we update our Yoast SEO plugin from version 22.6 to 22.7, the class for the FAQ block wp-block-yoast-faq-block and How-to block wp-block-yoast-how-to-block is missing.

Step-by-step reproduction instructions

1. Install the Yoast SEO free plugin of version 22.6

3. View the page and inspect the class for the blocks. You can see the FAQ block is outputted as <div class="schema-faq wp-block-yoast-faq-block"> and for the How-to block as <div class="schema-how-to wp-block-yoast-how-to-block">
4. Update the plugin to 22.7; you can notice the class for the FAQ changed to <div class="schema-faq"> whereas the How-to block outputted as <div class="schema-how-to wp-block-yoast-how-to-block">
5. However, when you try to create a new How-to block on another page, the class gets changes to <div class="schema-how-to">
