[PR] [python] Use a reserved host in the redirect user-info test fixture [flink-agents]

alnzng opened a new pull request, #1115:
URL: https://github.com/apache/flink-agents/pull/1115

   ### Purpose of change
   
   `test_rejects_redirect_user_info_without_leaking_secrets` builds its redirect `Location` from the live test server address:
   
   ```python
   target = base_url.removeprefix("http://")
   f"http://user:password@{target}/skills.zip?token=top-secret"
   ```
   
   Putting `user:password` on a live host is an anti-pattern — RFC 3986 §3.2.1 deprecates the format — and many organizations run secret-scanning rules that detect it. LinkedIn is one of them, and that makes this commit unpushable to our internal GitHub: the push is blocked on exactly this line.
   
   ```
   —— uri_secrets ——————————————————————————————
    locations:
      - commit: 0148970c7bd7f9c33f8897b878dde7ad059e91b6
        path: python/flink_agents/runtime/skill/tests/test_materialize.py:235
   ```
   
   Because the line is in committed history, it cannot be fixed downstream. Using the reserved `example.com` (RFC 2606) keeps the credential unambiguously synthetic, which is what the other 14 credential-bearing fixtures in this repo already do — none of them were flagged in the same push.
   
   ### Tests
   
   No new tests; this changes a fixture value in an existing test.
   
   The live address is not needed. `_SameProtocolRedirectHandler.redirect_request()` validates the target before delegating to the base handler, so the `ValueError` is raised before the redirect is followed and the host is never contacted. Redirect validation compares schemes only, never hosts, so the same code path is exercised. This matches `test_rejects_cross_protocol_redirect_before_request`, which hardcodes `https://127.0.0.1:1` for the same reason.
   
   The test still asserts the same `ValueError` matching `"must not include user info"`, and that neither `"password"` nor `"top-secret"` reaches the message.
   
   All 18 tests in `test_materialize.py` pass. `ruff check` and `ruff format --check` are clean.
   
   ### API
   
   No public API change.
   
   ### Documentation
   
   - [ ] `doc-needed`
   - [x] `doc-not-needed`
