Changed the nth-child selector to nth-of-type for Dynamic HTML blocks. When a Dynamic HTML block renders the row, it adds the section styles to a <style> tag as a sibling for each column div, which affects the nth-child selector. This change ensures that only the div elements are counted when applying some row styles.

Also, updated the selector for when row breakoutLeft/breakoutRight are used.
