[TASK] Mark PasswordPolicyValidator as public API

With the introduction of configurable password policies, the
`PasswordPolicyValidator` has been introduced. The class is
however marked as `@internal`, which basically was a mistake.
3rd party extensions providing users the possibility to change
a password should be able to validate the new password against
the globally configured password policy by using the
`isValidPassword()` method in the `PasswordPolicyValidator` class.

The change therefore mark the class as public API by removing
the `@internal` annotation.

Resolves: #101579
