[experiment] Stop testing promise_based_client_call due to leak (#35671)

There's roughly a 25% flake of a leak, blocking PR submission due to ASAN failures. Example: https://source.cloud.google.com/results/invocations/5d9fc8b9-c64f-4aaa-bbe6-2fb5f8fd0b24/targets/%2F%2Ftest%2Fcore%2Fend2end:negative_deadline_test@poller%3Dpoll@experiment%3Dpromise_based_client_call/log

Reproducible via: `bazel test --config=asan --test_env=GRPC_VERBOSITY=debug --test_filter='**' --test_sharding_strategy=disabled --runs_per_test=100 -- //test/core/end2end:negative_deadline_test@poller=poll@experiment=promise_based_client_call`

Closes #35671
