After this change OSSM-6830 we are using new bookinfo images. The bookinfo kube resources were updated in the `maistra-2.6` branch so the documentation should use the same branch too. (now, it uses `maistra-2.4` )
E.g.
https://docs.openshift.com/container-platform/4.16/service_mesh/v2x/ossm-create-mesh.html#ossm-tutorial-bookinfo-install_ossm-create-mesh

$ oc apply -n bookinfo -f https://raw.githubusercontent.com/Maistra/istio/maistra-2.4/samples/bookinfo/platform/kube/bookinfo.yaml  

The other resources are the same, but, I think, it wouldn't look good when one example has `maistra-2.4` and another has `maistra-2.6` so I suggest changing every occurrence of `maistra-2.4` to `maistra-2.6` in the documentation. ( I will check manually if there are any other differences between the resources, only images )
