bpo-32674: Improve the docstring for __import__ (GH-5339) (GH-5489)

Clarify that the level argument is used to determine whether to
perform absolute or relative imports: 0 is absolute, while a positive number
is the number of parent directories to search relative to the current module.
(cherry picked from commit 461d225b195eec5269f317323b41115516144c41)
