  `dacite` library doesn't compatible after 0.69.0 strawberry-graphql. (unhasable type 'StrawberryOptional' problem)
  I have a regression issue with StrawberryOptional (breaking changes in 0.69.0) 
  When I use dacite library to convert dict to strawberry.type class instance, it works in 0.67.x version. 
  
  ```
  from dacite import from_dict
  
  @strawberry.type
  class Tag:
      tag_id: int = None
      category: str = None
      images: List[str] = None
  
      @strawberry.field()
      def image(self, info: Info) -> Optional[str]:
          ...
  
  from_dict(data_class=Tag, data=dict(tag_id=34, category="song", images=["a", "b"]))
  // same with Tag(tag_id=34, category="song", images=["a", "b"]) 
  ```
  
  `dacite.from_dict` method convert `dict(**attributes)` to `Tag(tag_id=~, ...)` automatically. 
  It makes ORM model instance <-> Strawberry type instance conversion easily. 
  
  After upgrade, it occur an error unhashable type: 'StrawberryOptional'  because of Optional[str] type. 
  
  Can we make `StrawberryOptional`, `StrawberryList` to be hashable type to use dacite.from_dict ? 
  Or is there any alternative way to convert dict to strawberry.type instance?
