Remove unused KUBERNETES_VERSION and kubeconfig context setup

The KUBERNETES_VERSION variable and the set_kubeconfig_context function have been removed from create_cluster.sh since they were no longer in use. The README.md file was also updated with image placements for better visual presentation of the project. These changes contribute to cleaner, more efficient code.
