Pull request: test: add missing port=0 arg in test-debugger-extract-function-name

In the `test-debugger-extract-function-name` file the inspector port is not set to `0`, this causes the test (at least on my machine) to consistently (always) fail when run with the python runner with any repeat value greater than 1:
![test-debugger-fail](https://github.com/user-attachments/assets/8c3189f2-8a97-4ac4-b8dd-50f6b5ac4df4)

So I am making sure that the port is indeed set to `0` solving the issue.

Also the test has also been a bit flaky in the CI lately:
 - https://github.com/nodejs/reliability/issues/1246
 - https://github.com/nodejs/reliability/issues/1245
 - https://github.com/nodejs/reliability/issues/1244
 - https://github.com/nodejs/reliability/issues/1243
 - https://github.com/nodejs/reliability/issues/1242

So hopefully this change should address the flakiness :slightly_smiling_face: 

However I am not completely sure, since I did try to run some stress tests on the file on main:
- https://ci.nodejs.org/job/node-stress-single-test/591
- https://ci.nodejs.org/job/node-stress-single-test/592

But unfortunately they didn't show any flakes, so it is hard to confirm with full confidence whether
or not my changes are also addressing the CI flakes or not :confused:
