描述

Current problem

The PEP-8 guidelines state that module level dunders are supposed to be above imports. This is something pylint does not warn about if the code does not follow it.

Desired solution

Pylint should raise a warning if the above is not followed.

Additional context

Similar to #965, but also add a warning for it

研究方向
Review the existing implementation for a similar check in issue #965. Examine the pylint source code in 'pylint/checkers' to find where module level dunders are handled. Understand how to detect dunders below imports following PEP 8 guidelines. Consider how to add a new warning message and integrate it into the checker.
