[rest] Include Resource name in @doc when using TypeSpec.Rest.Resource.ResourceOperations

### Clear and concise description of the problem

I noticed in the playground using the REST Framework that the descriptions are not Resource specific.

For example:

```
description: Lists all instances of the resource.
```

When I would expect that it would say:

```
description: Lists all instances of Widget.
```

After some digging, I found out that you can pass in the Resource into @doc to provide this functionality:

```tsp
@doc("Lists all instances of {name}.", Resource)
```

But the REST Framework has not implemented this.
