The CI tested k8s v1.35.0 in the integrations so fat in the 1.19 release branch. In PR #17782 proposes to change the mergify config to require k8s v1.35.5 based tests to pass for release-1.19 and release-1.20. In order for that changed rule to possibly work, this Change adjusts the CI to run integration tests onk8s v1.35.5 in the release-1.19 CI. Signed-off-by: Michael Adam <obnox@samba.org>
