[Bug] Generic auth error is returned when password does not meet requirements

[LariozaFilament]

Description

With the Enforcement Mode set to Require Enforcement, passwords that don't meet the password requirements result in a generic AuthError.Failure.

Ideally I'd expect this to result in an error similar to the web sdk auth/password-does-not-meet-requirements. However resulting in AuthError.WeakPassword like when Enforcement Mode is set to Notify Enforcement would also help.

Also noting here that the auth/password-does-not-meet-requirements error is not documented in the web sdk docs.

Reproducing the issue

1. Set Enforcement mode to Require Enforcement
2. Attempt to create an account in the Unity editor, or in a mobile build.
3. --> Observe a generic Failure error is returned.
