OpenApi analyzers do not recognize returns in ternary expressions

### Is there an existing issue for this?

### Describe the bug

I enabled web API analyzers per [the docs](https://docs.microsoft.com/en-us/aspnet/core/web-api/advanced/analyzers) and was surprised to see no output. Long story short, the analyzer does not recognize returns in ternary expressions. All my controllers return like this:

```C#
return result != null ? Ok(result) : NotFound();
```

If I change this to an `if` expression, the analyzer highlights `NotFound()` and emits a warning as expected. But even then, it still does not warn that I have not documented what `Ok()` returns. I'm not sure if it's supposed to.

This may have been the issue underlying #26341.
