Satisfy OperationVariables constraint on generic

Building the front with Bun fails with the following error:
```
TS2344: Type 'U' does not satisfy the constraint 'OperationVariables'.

     6 | export function wrapQuery<D, T, U>(
  >  7 |   query: UseQueryReturn<T, U>,

     8 |   def: D,
     9 |   wrapper: (data: DeepRequired<DeepNonNullable<T>>) => D
    10 | ) {
```

This is due to an upstream type change in @apollo/client@3.7.6.
