This is the action item to implement the spec: doc/source/specs/2025.1/chart_versioning.rst Also add overrides env variables - OSH_VALUES_OVERRIDES_PATH - OSH_INFRA_VALUES_OVERRIDES_PATH This commit temporarily disables all jobs that involve scripts in the OSH git repo because they need to be updated to work with the new values_overrides structure in the OSH-infra repo. Once this is merged I4974785c904cf7c8730279854e3ad9b6b7c35498 all these disabled test jobs must be enabled.
