Validate if a string follows the Salesforce ID format pattern. A valid Salesforce ID is 15 or 18 characters long and contains only alphanumeric characters.
Examples:
Input: id = "0015f00000ZSL7hAAH"
Output: true
Explanation: This is a valid 18-character Salesforce ID
Input: id = "ABC123"
Output: false
Explanation: This string is too short to be a valid Salesforce ID
