test: delete ginkgo test "NodePort with L7 Policy from outside"

The test case was introduced to cover issue cilium#21954, but it turned out
the test is buggy and caused a number of CI flakes (cilium#25119).
Consequently, PR cilium#25236 put the test case under quarantine.

This commit removes that problematic test, as the target scenario has
been covered by connectivity test in cilium-cli
(cilium/cilium-cli#1547).
