chore: templatize provider in AuthorizationPolicy

With the old value, opendatahub-odh-auth-provider, the value would be
set, then almost immediately be reset to the value of
{{.AuthExtensionName}} (which appears to be equivalent to
<dsci.ApplicationNamespace>-auth-provider), via the separate manifest
specified in the following file, which gets applied by the same list
of resources in the feature:

z-migrations/kserve-predictor-authorizationpolicy.patch.tmpl.yaml

This causes a complication when watching the AuthorizationPolicy,
because it causes it to continuously update, flip-flopping between the
two values.

It seems to make more sense to just set the value to the expected
value from the outset, so that's what this change attempts to do.
