typo

Hello,
There is a typo in the code example on this page :
https://learnwagtail.com/tutorials/restricting-parent-and-child-pages/

parent_page_type instead of parent_page_types

Regards

Hi @maisim! Indeed there is a typo. They still try to ruin my life, even after 20+ years on a computer.

I know it's small, but do you think you'd be up for opening a PR to fix it?
