fix: add sentinel errors to excludedErrors in Test_PackageLevelErrorsMapped

The 4 subscription filter sentinel errors (ErrInteractiveRequired,
ErrNoSubscriptionsFound, ErrNoTenantsFound, ErrNoFilterExists) are
user-facing errors caught in sub-filter command actions and never
propagate to the telemetry MapError path.
