Implement a wait function that pauses the execution of code for a specified number of milliseconds. The wait function should return a Promise that resolves after the given time has elapsed.
Example usage
async function demo() {
console.log('Start');
await wait(2000); // Pauses for 2 seconds
console.log('End');
}
demo();
// Output:
// Start
// (waits for 2 seconds)
// End
