documentation correction for entra ID

[simra]

Describe the bug The documents at https://microsoft.github.io/TaskWeaver/docs/llms/aoai are incorrect for authentication using Entra ID.

The current documents indicate this configuration setting:

"llm.auth_mode":"default_azure_credential",

which throws an exception. The correct setting is

"llm.azure_ad.aad_auth_mode":"default_azure_credential",

Environment Information (please complete the following information):

• OS: WSL
• Python Version 3.11
• LLM that you're using: gpt-4o
• Other Configurations except the LLM api/key related: all other settings as indicated in the Entra auth docs. I was able to verify that the corrected configuration runs successfully for my endpoint.
