Update access arguments for the ml pipelines UI

I discovered an issue where users require cluster admin in order to be
able to access the ML Pipelines UI. Only view (or similar) level
permissions should be required on the namespace. This change modifies
the parameters for the ml pipelines oauth proxy to match what we're
using now in other pods in the ODH.
