This question runs in a pre-configured Salesforce environment - no personal connection required.
Write a method that makes an HTTP callout to fetch user data and return the user's age as an Integer.
You'll need to make a GET request to: https://dummyjson.com/users/{userId}
The API returns JSON in this format:
{
"id": 1,
"firstName": "Emily",
"lastName": "Johnson",
"age": 28,
"email": "emily.johnson@x.dummyjson.com",
"phone": "+81 965-431-3024",
"username": "emilys",
"birthDate": "1996-5-30"
}

Input: userId = 1

Input: userId = 5
Output: 30
Explanation: User with ID 5 has age 30
