Implemented PSR interface for JsonApiClient

[kocsismate]

Hi!

Thanks for the PR! However, the problem is that the current stable version (Yang 2.x) is still compatible with 7.2 where the return type variance is not supported, so the JsonApiResponse return type is not compatible with PSR-18's ResponseInterface.

Fortunately, Yang 3.0 is still in the works, and it requires PHP 7.4 at least, where variance is supported. So please change the target branch from master to 3.0.

Hi kocsismate,

Thank you for the comments. I have changed the target branch to 3.0.

Looks like there's a conflict. Can you please resolve it before I merge the PR?
