`OpenApiParameter` with Python `float` type is incorrectly labeled as `float` (32-bit) OpenAPI format rather than `double` (64-bit)

Describe the bug
OpenApiParameter with the native Python float type is formatted as a 32-bit float rather than 64-bit double.

Related to #674

To Reproduce

Use drf-spectacular 0.22.0.

input_param = OpenApiParameter(
    name="input",
    description="Description",
    type=float,
    default=1.0,
)


class MyViewSet(RetrieveModelMixin, GenericViewSet):
    @extend_schema(parameters=[input_param])
    def retrieve(self, request: Request, *args: Any, **kwargs: str) -> Response:
        ...

The resulting schema:

        schema:
          type: number
          format: float
          default: 1.0

Expected behavior

Expected schema

        schema:
          type: number
          format: double
          default: 1.0

well, that was a kind of obvious oversight, but iteration is our business, right? 😆

I can confirm that 0.22.1 fixes this issue. Thanks!
