Compat with Mypy 1.2.0

[g-as]

In python/mypy#14878, a new argument was added to DataclassAttribute (is_neither_frozen_nor_nonfrozen).

  File "/home/backend/.venv/lib/python3.10/site-packages/mypy/semanal.py", line 1743, in apply_class_plugin_hooks
    hook(ClassDefContext(defn, decorator, self))

    attributes = self.collect_attributes()
  File "/home/backend/.venv/lib/python3.10/site-packages/strawberry/ext/mypy_plugin.py", line 792, in collect_attributes
    attribute = DataclassAttribute(**params)
TypeError: DataclassAttribute.__init__() missing 1 required positional argument: 'is_neither_frozen_nor_nonfrozen'
