Describe the bug
When the CIVisibilityTestsApi.ListCIAppTestEventsWithPagination func is called, all errors are swallowed.

https://github.com/DataDog/datadog-api-client-go/blob/master/api/datadogV2/api_ci_visibility_tests.go#L243-L301

To Reproduce
Steps to reproduce the behavior:

• Run the function with no API credentials, which results in a 403 in the logs. But no error is returned from the function.

Expected behavior
I would expect errors to be caught in the async func and bubbled up to the calling function using channels or some other method.

Environment and Versions (please complete the following information):
v2 2.5.0
