assert Fix `implementsInterface()` PHPDoc

class_implements accepts either an object or a class-string, but the PHPDoc for the assert function is wrong and limits its functionality to a class-string only. I'm not entirely sure if this was on purpose, the README just mentions "Check that a class implements an interface", but it would work with either an instance of a class or a class-string and the assertion is under the "object" category.

See also https://phpstan.org/r/c72bb8af-4f27-462b-85f6-e2d3b81b9786 where this is tested in PHPStan (which just got support for PHPDoc-based type narrowing, this is not released yet)

I could not cleanly run psalm locally without unrelated errors, let's see what happens on CI 🤞

The docs look good, could you add some test cases using objects, so we cover it in our unit tests?

@BackEndTea in case you didn't see it: should be adapted. In case you're just busy: no worries, this is not important 😊
