Automate the following tests, so we can get them done more easily every time

          I did the following test:

• Created a notebook using the original image of the odh-notebook-controller before your changes.
  • notebook-b1 created at Nov 6, 2024, 11:35 AM
  • image: 'registry.redhat.io/openshift4/ose-oauth-proxy@sha256:4bef31eb993feb6f1096b51b4876c65a6fb1f4401fee97fa4f4542b6b7c9bc46'
• Changed odh-notebook-controller image to include your changes.
  • quay.io/opendatahub/odh-notebook-controller:pr-437
  • Created a new notebook-a1 at Nov 6, 2024, 11:41 AM
• Updated the oauth proxy image to on the odh-notebook-controller deployment to registry.redhat.io/openshift4/ose-oauth-proxy@sha256:4f8d66597feeb32bb18699326029f9a71a5aca4a57679d636b876377c2e95695
• Check if any notebook has been affected
  • Nothing change so far on the old deployed notebooks
• Created a new notebook and check the assigned oauth
  • c1 created at Nov 6, 2024, 11:46 AM
  • It has the new oauth image
  • The rest notebooks didn't get any restarts
• Till write you this message at 12.02pm nothing has changed on the notebooks
• One additional check was to restart the b1 and a1 notebooks and see if the oauthproxy image has been changed and it didn't which is good sign

So I would say /lgtm
