"Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s)."

My Angular app won't compile with rxfire 6.0.5. The error is

```
Error: node_modules/rxfire/firestore/lite/interfaces.d.ts:8:29 - error TS2314: Generic type 'AggregateQuerySnapshot' requires 1 type argument(s).

8 export type CountSnapshot = lite.AggregateQuerySnapshot<{
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
9 count: lite.AggregateField;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 }, any, DocumentData>;
~~~~~~~~~~~~~~~~~~~~~
```

This is with Firebase 9.23.0. I can't get Firebase 10 to work, see my[ StackOverflow question]((https://stackoverflow.com/questions/77024782/what-is-a-firebase-app-no-firebase-app-default-has-been-created-call-i)).
