Latest Posts: Add missing class to post title

[ndiego]

Description

The Latest Posts block outputs CSS classes for every element except the post title, which makes it hard to style the post title with custom CSS. This PR simply adds the wp-block-latest-posts__post-title class.

Testing Instructions

1. Use Twenty Twenty-Two or similar theme.
2. Add the Latest Posts block to a page.
3. Check the frontend and Editor view look the same and that the wp-block-latest-posts__post-title class is added to the post titles.

Hi,
I think this is not correct.
Why the post title class is added (only in Editor) to the featured image element and not to the post title element?
I've set styles for the post title to apply to both (frontend and Editor) and in the Editor these styles are applying to the featured image.

In the Editor, the class for the Post title (.wp-block-latest-posts__post-title) is on the feature image HTML element, and the post title element doesn't have the class.

That's why the styles I've defined for that block look wrong in the Editor.

@ndiego @carolinan I don't know if I should open another issue for this. Let me know

@adrianahdez HI
Yes, if there isn't already an issue, please open a new issue, because it is not as discoverable here. Fewer people will find it here.
