`test_pools_num_jobs_basic` fail on shared gke server test

[zpoint]

Pass on nightly k8s remote server tests : https://buildkite.com/skypilot-1/smoke-tests/builds/5692#_ pytest tests/smoke_tests/test_pools.py::test_pools_num_jobs_basic --kubernetes --remote-server

Fail on shared GKE postgres tests: https://buildkite.com/skypilot-1/nightly-build-shared-gke-api-server/builds/7 pytest tests/smoke_tests/test_pools.py::test_pools_num_jobs_basic --kubernetes --env-file s3://buildkite-configfile-test/test_gke_config_2.yaml

Because we are including the shared GKE postgres tests on nightly, I have disabled this test in this #7830

It looks like the API server is not responding or log corrupted somehow, we should fix this and remove the no_remote_server mark
