[ServiceBus][Test] Fix Min-Max test build failure (Azure#19600)

* [ServiceBus][Test] Fix Min-Max test build failure

With `@types/long` min version of `4.0.0` we got compilation error

```
Namespace 'Long' has no exported member 'Long'.
```

version `4.0.1` fixes this.

* Update version for event hubs too
