Twenty-Twenty: Fix paragraph block alignment issues when used on a RTL website.

Twenty Twenty's `style.css` file has `/*rtl:ignore*/` for the `.has-text-align-left` class, but that was previously missing from the `.has-text-align-right` class. As a result, the theme overrides block library styles on the front-end (and not in the editor). This changeset adds the missing declaration.

Fixes #49447.
