feat(test): Add tests for it locale

This commit introduces tests for the Italian (`it`) locale.
Following the existing test structure, three new test files have been added:
- `test/it/it_casual.test.ts`: For casual date expressions.
- `test/it/it_weekday.test.ts`: For weekday expressions.
- `test/it/it_month_name_little_endian.test.ts`: For month name expressions.
