Correct the import source of OrderedDict

[WH-2099]

OrderedDict should be imported from collections rather than typing.
The OrderedDict in typing is only used for type annotations and has been marked as deprecated since version 3.9.

It's not only for type annotations, it's more of an alias with typing support.

We still support Python 3.8. We'll update all these imports (likely automatically with pyupgrade or similar) once we drop Python 3.8.
