Add support for PHPStan 2 (#348)

This PR includes a lot of changes to pass CI.

### requiments, dependency
- Update requirements PHPUnit >=9.1 .
  - Becaouse, run test with  PHPUnit 8 would cause deprecation warning.
  - PHPUnit 9 requires PHP 7.3, and PHPStan requires PHP 7.4. So update requirements is acceptable, I think.
- Add requiments [phpspec/prophecy-phpunit](1470fd3)
- Update php-cs-fixer 2 to 3. ( `.php_cs` to `.php-cs-fixer.php`)
  - to run under  recent PHP 8 versions
  - I'm not familiar with php-cs-fixer, so if you find any problem, please tell me.
### tests
-  [Use PHP's reflection to get stub object, instead of prophesize() call](315866a)
   - PHPStan 2's `Reflection\ClassReflection` is final class.
   - I can't see any good reason to use `prophesize()` in these unit tests.
