[Scripting] Sleep function only works when used with 'await'

[kics223w1]

Description

The sleep function in the Scripting Tool only works when used with the await keyword.

---

Steps to Reproduce

async function onRequest(context, url, request) {
    console.log(url);

    // This line will NOT delay execution
    sleep(5000);

    return request;
}

Current Behavior

• The sleep function only works correctly when prefixed with await.

Expected Behavior

• The sleep function should work as intended even without the await prefix.

Environment
