Use Face Admin Client to Manage Large Person Group

[der3318]

Purpose

The PR updates several face sample codes that are referenced by learn.microsoft.com. The primary goal is to migrate to the latest version of SDKs, allowing developers to manage face collections (e.g., large person group and large face list) via an administration client.

Language	SDK	Pull Request	Version Change
C#	Azure.AI.Vision.Face	Azure/azure-sdk-for-net#45402	1.0.0-beta.1 ➡️ 1.0.0-beta.2
Python	azure.ai.vision.face	Azure/azure-sdk-for-python#37044	1.0.0b1 ➡️ 1.0.0b2
Java	com.azure:azure-ai-vision-face	Azure/azure-sdk-for-java#41823 Azure/azure-sdk-for-java#42239	1.0.0-beta.1 ➡️ 1.0.0-beta.2

And a couple of minor modifications:

• Explicitly and clearly set recognition model to 04 in the demo of "find similar faces".
• The recommended C# naming convention is to use PascalCasing for constants, and camelCase for method parameters.
• Python, on the other hand, should use snake_case to name variables.
• Fix the breaking change related to Python's FaceDetectionModel and FaceRecognitionModel enum. For example, change "DETECTION_03" to "DETECTION03".

Does this introduce a breaking change?

• Yes
• No
