Update the correct indentation for tolerations.

The indentation in section "2. Edit the ingresscontroller resource and change the nodeSelector to use the infra label:"  for "tolerations" is wrong. The "tolerations" must be an attribute of "nodePlacement:" and not of "spec:".

 <1> Add a `nodeSelector` parameter with the appropriate value to the component you want to move. You can use a `nodeSelector` in the format shown or use `<key>: <value>` pairs, based on the value specified for the node. If you added a taint to the infrastructure node, also add a matching toleration.
