Describe the bug

After migration from 0.7 to 0.9 version of Kratos, when attempting to call new API /admin/identities/{id}/sessions method (for the user who had at least one session in the past) via Java Kratos API client, following exception occurs:

java.lang.IllegalArgumentException: Unexpected value 'v0.6_legacy_session'
	at sh.ory.kratos.model.SessionAuthenticationMethod$MethodEnum.fromValue(SessionAuthenticationMethod.java:81) ~[kratos-client-0.9.0-alpha.3.jar!/:na]

It can be observed, that enum in SDK code does not indeed have required value:

 public enum MethodEnum {
    LINK_RECOVERY("link_recovery"),
    
    PASSWORD("password"),
    
    TOTP("totp"),
    
    OIDC("oidc"),
    
    WEBAUTHN("webauthn"),
    
    LOOKUP_SECRET("lookup_secret");

Reproducing the bug

1. Deploy a custom platform with Kratos 0.7 integrated.
2. Create a user and login.
3. Migrate platform to Kratos 0.9 version.
4. Request user sessions using Java Kratos SDK.
