Announcing review approval process changes

Hi contributors! On behalf of our infra team, I’d like to announce a consensus reached last week.

UPDATE: Changes deployed since 2021-05-31

We are supporting multiple kind of review approval (LGTM) reactions so far. From time to time it causes a number of confusions and build unnecessary approaches since GitHub already provide such mechanism.

You can see the decision making progress on the issue and we are gonna drop support of /lgtm alike review approval reactions in the near future.

Comment on the issue if you have further concern.
