Count the number of key-value pairs in a map where the value is greater than a specified threshold.

Examples:

Input: numberMap = {1: 5, 2: 10, 3: 15, 4: 20}, threshold = 12 Output: 2 Explanation: The values 15 and 20 are greater than 12, so there are 2 key-value pairs that satisfy the condition Input: numberMap = {1: 100, 2: 200, 3: 300}, threshold = 50 Output: 3 Explanation: All values (100, 200, 300) are greater than 50, so there are 3 key-value pairs that satisfy the condition
