[bug] Python SDK doesn't work as expected for HEAD as boolean

[msyyc]

If emitters are doing head as boolean, it should be:

• 2xx is true
• 404 is false
• everything else is an error that needs to be thrown (as usual)

Current Python SDK doesn't work as ecpected:

	raise HttpResponseError(response=response)
	if cls:
	return cls(pipeline_response, None, {}) # type: ignore
	return 200 <= response.status_code <= 299
