[fix][ci] Fix PulsarFunctionLocalRunTest that broke after ClusterData validation changes

[lhotari]

Motivation

"Pulsar CI Flaky" builds fail with OOMEs and produces heap dumps.
It turns out that #19151 causes a breaking change.

In PulsarFunctionLocalRunTest, the line 275 ClusterData clusterData = ClusterData.builder().serviceUrl(urlTls.toString()).build(); didn't cause the test to fail before #19151 changes.
After the changes were made, this test started failing, but the test failure was ignored.

Modifications

• Fix the test
• Make changes to the test that prevent the resource leak that leads to a OOME
