Revert "[v1.9-branch] RHOAIENG-10827: feat(nbcs): update ose-oauth-pr…

…oxy image digest reference from 4.8 to the latest 4.14 version (opendatahub-io#388)"

We found at least one OCP cluster where this change causes restart of running notebooks when controller is updated from a previous version
to a version with this fix present. To be safe, we'll roll this back and try again. We'll investigate that cluster to understand what's happening.

This reverts commit 99e70bf.
