ansible-role-kubeflow 1.1.0

Targets AIaaS platform 260301.1.0 (KCD 26.03.1).

Requires the manifests repository at >= 260301.0.0: the role now invokes
manifests/scripts/aiaas-install.sh and applies manifests/aiaas/overlays/prod.
Older tags use manifests/hack/kaap-*.sh and manifests/kaap/ and will fail at
the first script call.

Also in this tag, from the 25 commits accumulated since 1.0.0: Gateway API and
Envoy AI Gateway installation, CVMFS CSI plugin, CSI-S3 profile PV support,
Longhorn S3 backup target, and RAGFlow OIDC fixes.

Backwards compatible for callers: kaap_manifests_* variables still work as
deprecated aliases of the new aiaas_manifests_* names.
