change type signature of cardinality from any to type var (facebookin…

…cubator#10416)

Summary: 'any' is now treated as a concrete type by our underlying system, xstream. we need the signature to indicate it explicitly to be a type var.

Test Plan:
```
make unittest
```

it fails on 8 tests but are the same tests that fail on the main branch.
