Fix BC break add missing method `ProviderInterface::getHolidays`

[ghost]

In the previous version Yasumi\Yasumi::create was returning Yasumi\Provider\AbstractProvider now its return Yasumi\ProviderInterface without method getHolidays . Even tests expects that ProviderInterface::getHolidays exists for example Yasumi\tests\Base\YasumiTest::testRemoveHoliday

@jwojtyra-aterian Thank you very much for the PR. Could give me an example of how this would break things? All tests are successful (Unless the tests missed something :) )

Sure, an example from this repo, I run phpstan with current configuration but for some tests ./vendor/bin/phpstan analyse tests/Base here is part of the output. For the same reason I cannot upgrade yasumi in my project

@jwojtyra-aterian Indeed, the test classes are not yet following the checks as the base code (src) does. You should run phpstan with the provided phpstan config (phpstan.neon.dist) or use the included composer script composer phpstan.

Not sure I understand why you can't upgrade Yasumi in your project. PHPStan does not look at vendor packages when you use Yasumi as a composer package.

[ghost]

Yes but just like wrote at the beginning, I use method getHolidays and previously Yasumi::create returns AbstractProvider that have this method, now it returns ProviderInterface without this method. And PHPStan finds those errors in the codebase.

[stelgenhof]

Ah, you mean when using PHPStan for your own project?

[ghost]

yes

[stelgenhof]

I see, Sorry it wasn't immediately clear to me from your description. I'll make a fix for this.
