workflows,tox: disable warning for new pylints

Starting from the pylint version that is pulled with Python 3.9,
it checks for the amount of positional arguments in a function.
The __init__ function has too many and the warning can only be
disabled for newer versions, therefore tox has to conditionally
check it.
