Allow date field to be blank when it is a required field

[ncla]

This would help prevent content editors from going into auto-pilot assuming that the date field is already filled out correctly.

The date field automatically defaults to current date if it is required. Removing the required validation, the field displays "Add date" button, which is what I want if the field is required and has default value set to empty.

Adding manually to blueprint .yaml file field property default: "" does not make the input field blank.

I think there should be a setting for default to current date if required instead
