The version of Armada deployed by Airskiff was recently uplifted. The
gate erroneously uses the latest version of OSH-infra, so there was no
impact; however, users of the 005-make-airship script experience a
Tiller version mismatch due to an older version of K8s. This change
uplifts the OSH-infra pin to prevent errors.
