[Bug]: [http-client-python] unused ErrorDetails model exposed

[kristapratico]

Describe the bug

An ErrorDetails model is exposed under models that is not used in the API.

APIview: https://spa.apiview.dev/review/d48830fcdd2c4713b6344d61ae626d5e?activeApiRevisionId=e6f9f621b7d546c1b7ee68713dddac62

Apparently, it is being used as an error output, but we should have a way to hide it from the public surface.

Hi @kristapratico, ErrorDetails is actually used when http response error is raised which is not showed in ApiView:

[yurinh-microsoft]

@msyyc can we resolve/close this bug then?
