Update version of dependency pylint

Newer version of pylint have deprecated the __implements__ class
attribute, but removing that causes earlier versions of pylint to miss
checkers. https://github.com/pylint-dev/pylint/blob/f815e9f5fcdd5caffc04e335fc4590a65989ef21/doc/whatsnew/2/2.14/full.rst#L196
