Make tests not Dependent on Demo Server

[bupd]

Instead of running test against the "demo.goharbor.io". Create a dagger service running harbor and run tests against it.

This way no external service is required & not need to be maintained.

This should be the way.

Notes

We can make use of harbor in dagger: https://github.com/container-registry/harbor-next/tree/build/daggerize
