Make some @objc methods public so WordPressData can access them

I never looked into it, but apparently the `public` access level for
`@objc` is required in a framework setup for those methods to be
accessible through the `<framework name>-Swift.h` generated header.

We run into the same issue in Keystone, see
#24383
