Improving the creating-clusters-baremetal tutorial in KubeOne docs

[ttuellmann]

This fixes three minor issues in the KubeOne tutorial "Creating a Kubernetes Cluster on Bare-Metal":

• The number of control plane nodes should be odd rather than even
• The manifest in step 3 used the taint node-role.kubernetes.io/master on the control plane nodes, which has been removed in all supported K8s releases.
• I bumped the K8s release to 1.32.3 in the manifest

Hi @ttuellmann. Thanks for your PR.

I'm waiting for a kubermatic member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
