Notion.so RTL support for written text

Add support for writing RTL text blocks (including todo list, bullet list, headings, etc.) Text will change direction automatically depending on the language of the first letter in a text block. (Thus, English text will remain with the same behavior) Could be helpful if you want to write a text or todo list in your RTL language. Multiple languages with different directions can be written on the same page. This script is not supposed to change the direction of databases views nor its inner cells
