Improve test data structure and coverage in test_nice_year section.

Several improvements are needed for better test data structure and coverage:

1. Use proper JSON array format for datetime_param instead of comma-separated strings
2. Use JSON boolean values instead of strings for the "bc" field
3. Add missing test cases for edge scenarios

Apply these changes to improve the test data structure:

  "test_nice_year": {
-   "1": {"datetime_param": "1, 1, 31, 13, 22, 3", "bc": "True", "assertEqual": "one b.c." },
+   "1": {"datetime_param": [1, 1, 31, 13, 22, 3], "bc": true, "assertEqual": "one B.C." },

Consider adding these test cases:

{
  "25": {"datetime_param": [0, 1, 31, 13, 22, 3], "bc": false, "assertEqual": "zero"},
  "26": {"datetime_param": [9999, 1, 31, 13, 22, 3], "bc": false, "assertEqual": "nine thousand nine hundred ninety nine"},
  "27": {"datetime_param": [10000, 1, 31, 13, 22, 3], "bc": false, "assertEqual": "ten thousand"}
}
