- Updates the default text in the editor to match the default text on the front.
- Removes the editor styles, since the styles made the block look different than on the front.

- Replaces the onKeyDown behaviour with the Richtext prop disableLineBreaks, and uses __unstablOnSplitAtEnd to insert a new paragraph block if the user clicks on enter at the end of the block's text content.
