GetFromJsonAsync should have proper list of thrown exceptions

[LeftTwixWand]

Describe the issue or suggestion

Currently, httpClient.GetFromJsonAsync documentation shows, that the only one thrown exception is OperationCancelledException.
But it's not true and there is at least HttpRequestException which contains status code.
And might be JsonException as well.

I think, it would be quite useful to include more exceptions into the docs.
Why this was inconvenient for me - I can't write proper resiliency policies because I don't know the excections, which are thrown by default.

Ultimately, GetFromJsonAsync is just an accelerator method that can surface exceptions from a number of components containing abstractions:

1. The HttpClientHadler implementation used by HttpClient
2. Any JsonConverter<T> implementations used by JsonSerializer.

We don't typically document failure modes that could potentially surface from abstractions, since it may produce exceptions of any type.
