Subject: [PATCH] feat(ol/feature): allow generics for
 `feature.getProperties<T>()`

with this change it's possible to pass a generic type `T` when calling `feature.getProperties<T>()` and using with TypeScript.

```
// before: const stop = feature?.getProperties() as Stop
const stop = feature?.getProperties<Stop>()
console.log(typeof stop) // "Stop"
```

closes #14868
