Twenty Ten: Pullquote block paragraph text is too small in editor with WP6.1

[sabernhardt]

On the front end, the Pullquote paragraph is 1.5em (24 pixels in the post content). In the editor, the paragraph's 16-pixel font size matches the citation's size with WordPress 6.1 beta 2.

In (at least) 5.9 and 6.0, the editor had set the font size to 28px, and ​Gutenberg PR 43195 removed the font size. Before that, the theme had specified 1.5em when the editor used the .editor-rich-text class, which was removed from the div wrapper (and the div is also gone in 6.1).

Before: font size is 16 pixels in the editor

With patch: font size is 24px for paragraph, 16px for citation

Other themes may need to change the font size, too.

Twenty Ten: Adjust Pullquote Block paragraph font size.

This changeset adjusts the size of paragraphs located inside the Pullquote block to account for changes introduced in ​Gutenberg PR 43195. This ensures the size of the paragraph is set to 1.5em in the editor.
