[Python APIView] Overloaded methods are rendered without showing the final implementation

**Bad code snippet:**
```python
def create_or_update(
```
In APIView, overloaded methods such as `create_or_update` are rendered without displaying the final implementation, which should be decorated with `@distributed_trace`. This misrepresents the actual code structure and omits important implementation details.

**Expected behavior:**
APIView should render both the overloads and the final implementation of the method, including any decorators such as `@distributed_trace`.

**Good code snippet:**
```python
@distributed_trace
def create_or_update(
...
```
This ensures that viewers of APIView see the complete method definition, including its implementation and relevant decorators.

Start in the APIView rendering or parsing path for Python methods and trace how the create_or_update definition is handled. Reproduce the rendering with the provided overloaded-method example, then compare the output with the source, including the @distributed_trace decorator. Done means APIView displays both overloads and the final implementation.
