cluster-api-provider-rke2 version upgrade to 0.21.1 for fix in https://github.com/rancher/cluster-api-provider-rke2/pull/768

[miloaissatu]

What steps did you take and what happened?

Create a 1.33.x cluster and upgrade it to 1.34.x, or deploy a new 1.34.x cluster. Machines will be stuck with

2m36s       Warning   ControlPlaneUnhealthy   rke2controlplane/machinename   Waiting for control plane to pass preflight checks to continue reconciliation: [machine machinename reports AgentHealthy condition is false (Error, Missing node), machine machinename does not have EtcdMemberHealthy condition]

The machine itself is running and ready. This is due to a control plane label change. cluster-api-provider-rke2 bug was done to support 1.34.1. github automation marked it as 'done' in capi/turtles project as well 3 weeks ago here: rancher/cluster-api-provider-rke2#760.

I tried my luck bumping the rke2 version via turtles helm chart by doing cluster-api-operator.cluster-api.rke2.version: "v0.21.1" but the turtles control manager log gave
