kubeadm: apply changes around "master" taint for 1.25

Browse Source 
The "master" taint is no longer applied on control plane
nodes by kubeadm 1.25.

Remove mentions of the taint from the documentation:
- implementation details
- create a kubeadm cluster
- known labels / taints

As soon as the control plane is available, kubeadm executes following actions:
- Labels the node as control-plane with `node-role.kubernetes.io/control-plane=""`
- Taints the node with `node-role.kubernetes.io/master:NoSchedule` and `node-role.kubernetes.io/control-plane:NoSchedule`
- Taints the node with `node-role.kubernetes.io/control-plane:NoSchedule`
Please note that:
1. The `node-role.kubernetes.io/master` taint is deprecated and will be removed in kubeadm version 1.25
1. Mark control-plane phase phase can be invoked individually with the [`kubeadm init phase mark-control-plane`](/docs/reference/setup-tools/kubeadm/kubeadm-init-phase/#cmd-phase-mark-control-plane) command
Please note that the phase to mark the control-plane phase phase can be invoked
individually with the [`kubeadm init phase mark-control-plane`](/docs/reference/setup-tools/kubeadm/kubeadm-init-phase/#cmd-phase-mark-control-plane) command.
