This looks good to me,
just some nitpick questions

[atheo89]

@harshad16 Thanks for noticing the overriding while the restart of the notebook. I added the logic on the runtime-script to check if an extension already exists. It works now as expected.
Tested with this latest image: quay.io/rh_ee_atheodor/workbench-images@sha256:7ee0cf657d3c287523a5ed155a6fcb009a7aa686ffe828b7eb08e4e27b664048 (Also in the PR description)
