Fix failures in CI

[martinkunkel2]

Fixed multiple issues that causes the CI failures on main:

• one link in markdown file
• cargo clippy warnings (rust 1.93.0)
• tokens and certificates: update from kuksa-common
• pytest: pin version to less than 9 as workaround for a deprecated method that became an error in pytest 9

Update of certificates in kuksa-common:
eclipse-kuksa/kuksa-common#11

hey @martinkunkel2 thanks for the contribution. Quick question just to check back: Whats the reason to use pytest less than version 9 is there some trouble with the newer versions?

[lukasmittag]

LGTM

[martinkunkel2]

@lukasmittag reason for the pytest version pinning is this deprecation warning:

integration_test/test_databroker.py::test_events PASSED                  [100%]

=============================== warnings summary ===============================
integration_test/test_databroker.py::test_feeder_metadata_registered
  /home/runner/work/kuksa-databroker/kuksa-databroker/.venv/lib/python3.12/site-packages/_pytest/fixtures.py:1182: PytestRemovedIn9Warning: 'test_feeder_metadata_registered' requested an async fixture 'setup_helper', with no plugin or hook that handled it. This is usually an error, as pytest does not natively support it. This will turn into an error in pytest 9.
  See: https://docs.pytest.org/en/stable/deprecations.html#sync-test-depending-on-async-fixture

without the version pinning, pytest 9 is used which fails.

@lukasmittag : if possible, please also review eclipse-kuksa/kuksa-common#11. So that the certificates files in this repo and kuksa-common are in sync.

[martinkunkel2]

@lukasmittag Thank you for merging eclipse-kuksa/kuksa-common#11.
The certificates are the same on this PR. Can this PR also be merged?
