Add new approvers to eventing-natss

@astelmashenko and I have been heavily involved in the improvement of the JetStream support in eventing-natss and would like to become approvers of the project.

At the moment the only approver is @zhaojizhuang, if you would like to provide your 👍 or some feedback on anything better we can do?

Thanks
