Describe your changes
The validator was not supporting types without args. For example:

>>> from unittest.mock import MagicMock
>>> from attrs_strict import type_validator
>>>
>>> attr = MagicMock()
>>> attr.name = "zoo"
>>> attr.type = list
>>>
>>> type_validator()(None, attr, [1, 2, 3])

AttributeError: type object 'list' has no attribute '__args__'

This PR fixes it for lists, dicts, and tuples.
