Reverts the editor's paragraph navigation behavior that was changed in
#47734. Whitespace-only lines are now treated as paragraph boundaries
again for non-vim mode users.
Vim mode retains its own implementation where only truly empty lines
are paragraph boundaries.
Release Notes:
- Fixed editor paragraph navigation to treat whitespace-only lines as
paragraph boundaries again
