fix(frontend): type error in useServiceUsageQuery.ts (#6081)

### 💭 Notes

Without the change I was getting this error:

```ERROR in ./jsapp/js/account/usage/useServiceUsageQuery.ts:135:3
TS2322: Type 'UseQueryResult<UsageState | undefined, Error>' is not assignable to type 'UseQueryResult<UsageState>'.
  Type 'QueryObserverRefetchErrorResult<UsageState | undefined, Error>' is not assignable to type 'UseQueryResult<UsageState>'.
    Type 'QueryObserverRefetchErrorResult<UsageState | undefined, Error>' is not assignable to type 'QueryObserverRefetchErrorResult<UsageState, Error>'.
      Type 'UsageState | undefined' is not assignable to type 'UsageState'.

    133 |   }, [params?.shouldForceInvalidation])
    134 |
  > 135 |   return useQuery({
        |   ^^^^^^
    136 |     queryKey: [QueryKeys.serviceUsage, organizationData?.id],
    137 |     queryFn: () => loadUsage(organizationData?.id || null),
    138 |     // A low stale time is needed to avoid calling the API twice on some situations
```

I remember I was getting the same error after bumping some react-query
related dependency. But now I started getting this on `main` without the
bump.
