[Hawk777]

Steps to reproduce

1. Lint the code print(http.HTTPStatus(404).phrase).

Current behavior

test.py:2:6: E1101: Instance of 'HTTPStatus' has no 'phrase' member (no-member)

Expected behavior

No errors.

pylint --version output

This looks a bit like #2950, but that was apparently fixed prior to astroid 2.3.3 (at least based on the commit date, Astroid 2.3.3 was released on November 6 while #2950 was closed on September 12, so I assume it contains the fix) and referred to accessing enum members via their named constants rather than by the constructor. It also looks a bit like #2626, but that is about methods while this is about data members; also, it seems that #2950 was fixed by making Astroid explicitly aware of HTTPStatus, whereas #2626 is about a custom enum, so it seems like a separate issue.
