Missing closing figure tag in quote_block.html

[sysaeon]

Describe the bug

The missing </figure> tag in quote_block.html causes any custom CSS classes applied to quotes to affect all the following elements on the page.

Steps to reproduce

Steps to reproduce the behavior: (I was working on a Blog Article page at the time)

1. While editing a page, place a quote block above a text block with some content in both.
2. At the quote block, click on Advanced Settings and add text-center as a Custom CSS Class.
3. In the preview pane, watch the text in both blocks move to the center.

Expected behavior

Only the text in the quote block should center.

Additional context

I added the missing tag and it works as expected.

{% endif %}
</figure>
{% endblock %}
