mismatch of documentation and published SDK

### Type of issue

Code doesn't work

### Description
Your default code generated by foundry playground:
```
from azure.ai.projects import AIProjectClient
from azure.identity import DefaultAzureCredential
from azure.ai.agents.models import ListSortOrder

project = AIProjectClient(
credential=DefaultAzureCredential(),
endpoint="XXXX"
)

agent = project.agents.get_agent("XXXX")
```

**does not work!**

your online documentation says it should, because the class should contain `agents` based on class `AgentsClient`, which should contain `get_agent()` but in reality

```
azure-ai-projects 2.0.0b3

.../azure/ai/projects/_client.py
```

```
class AIProjectClient: # pylint: disable=too-many-instance-attributes
"""AIProjectClient.

:ivar agents: AgentsOperations operations
:vartype agents: azure.ai.projects.operations.AgentsOperations
```

the `agents` is is type `AgentsOperations`!!!

**Publish SDK that you describe by documentation!**
