Internal

• CI: pin to Helm v4.2.0 in the integration tests. (#1396)
• Pin pytest to <9 in the ess-community-integration-tests package as well, so downstream consumers that uv tool install the test package (rather than running from the locked workspace) don't pull pytest 9, which breaks pytest-asyncio-cooperative. Completes the pin from #1301. (#1411)
