Entity.createFromDiscriminatorValue incorrectly deserializes #microsoft.graph.user as com.microsoft.graph.beta.models.security.User

從所引用行中的產生模型 models/Entity.java 判別器工廠開始，並將其 imports 和型別對應與 DirectoryObject::createFromDiscriminatorValue 進行比較。執行提供的 KiotaJsonSerialization 重現，接著為 #microsoft.graph.user 新增回歸涵蓋範圍，並檢查其他判別器對應是否存在相同的歧義。

Describe the bug

In current beta version, when trying to deserialize a #microsoft.graph.user from JSON using KiotaJsonSerialization.deserialize(json, Entity::createFromDiscriminatorValue), it's returned as a com.microsoft.graph.beta.models.security.User instance.

This is because only one of com.microsoft.graph.beta.models.User and com.microsoft.graph.beta.models.security.User is imported the latter), and classes are referenced without fully qualified name.

See https://github.com/microsoftgraph/msgraph-beta-sdk-java/blob/3612a3a8958cc35b0be7626b966008ea99a031af/src/main/java/com/microsoft/graph/beta/generated/models/Entity.java#L2075 and https://github.com/microsoftgraph/msgraph-beta-sdk-java/blob/3612a3a8958cc35b0be7626b966008ea99a031af/src/main/java/com/microsoft/graph/beta/generated/models/Entity.java#L2326

There are probably other cases like this one.

Expected behavior

KiotaJsonSerialization.deserialize(json, Entity::createFromDiscriminatorValue) should return a com.microsoft.graph.beta.models.User instance for #microsoft.graph.user objects.

How to reproduce

This test

//passes
assertEquals(com.microsoft.graph.beta.models.User.class, KiotaJsonSerialization.deserialize("""
        {
            "@odata.type": "#microsoft.graph.user"
        }
        """, DirectoryObject::createFromDiscriminatorValue).getClass());
//KO
assertEquals(com.microsoft.graph.beta.models.User.class, KiotaJsonSerialization.deserialize("""
        {
            "@odata.type": "#microsoft.graph.user"
        }
        """, Entity::createFromDiscriminatorValue).getClass());

will fail with

org.opentest4j.AssertionFailedError: 
Expected :class com.microsoft.graph.beta.models.User
Actual   :class com.microsoft.graph.beta.models.security.User
