### Describe the bug

When trying to retrieve a `RateLimiter` with `Env::get_binding` the following error occurs:

```
Binding cannot be cast to the type RateLimiter from Ratelimit
```

### Steps To Reproduce

I have the following in my `wrangler.toml`:

```toml
[[unsafe.bindings]]
name = "MY_RATE_LIMITER"
type = "ratelimit"
namespace_id = "1001"
simple = { limit = 10, period = 60}
```

And the rate limiter is being retrieved like so:

```rs
// ...

let rate_limiter = cx
.env
.get_binding::("MY_RATE_LIMITER")?;

let rate_limit_outcome = rate_limiter
.limit(format!("user_id:{}", claims.user_id))
.await?;
if !rate_limit_outcome.success {
return Response::error(
"Rate limit exceeded.",
StatusCode::TOO_MANY_REQUESTS.as_u16(),
);
}
```
