How to create an integer enum

The following enum:

```
import "@typespec/rest";
import "@typespec/openapi3";

...

enum DayOfWeek
{
Monday: 0,
Tuesday: 1,
Wednesday: 2,
Thrusday: 3,
Friday: 4,
Saturday: 5,
Sunday: 6
}
```

Generates a `number` enum. Is there any decorator (or way) to force it to an int32 enum? I did try to find something in the documentation without luck.
