Add aliok as one approver of knative operator (#389)

Ali has done amazing work, even since he was not officially joined the Knative
community.

He has leading the effort in operator's release in operatorhub, contributing
across any aspects, testing the operators against multiple scenarios.

His strong review has also acted as a good goalkeep of our repository.

Based on his general contribution during the past3 months, I would like
to add his as an approver.
