Kubernetes version support

Every Kubernetes version you request is validated at bootstrap. It must:

• start with v — for example v1.34.0;
• be a released version that is not past end-of-life — end-of-life is checked against endoflife.date data baked into the binary (refresh it with make fetch-k8s-eol);
• be within the range supported for your provider:

KubeAid CLI	AWS · Azure · Hetzner (Cluster API)	Bare metal (KubeOne)
v0.31.x	v1.30 → latest released (non-EOL)	v1.33 – v1.35

• Cluster API clouds — v1.30 up to the latest released minor.
• Bare metal — fixed to v1.33–v1.35 by KubeOne v1.13; the range moves when KubeOne is upgraded.
• KubePrometheus — matched to the Kubernetes version automatically, over v1.32–v1.36 (cgroup v1 support ends at v1.35).

Maintainers: update the table each release when the supported range, KubeOne version, or a pinned component changes.
