Test: Remove gRPC Fortune Teller.

[Gacko]

What this PR does / why we need it:

This PR removes a test case from the gRPC tests that was using the gRPC Fortune Teller image, as this image is quite old and not supporting modern image manifest formats anymore. It therefore was blocking us from bumping KIND to more recent versions, as these contain containerd v2, which does not support the before mentioned image manifests anymore.

The main purpose of this test, checking if grpc_pass is being set in the nginx.conf, is also checked in the following tests.
