These rules for Mergify do the following:
1. dismiss review +1's when a PR is updated
but keep any -1 reviews, so the reviewer needs to confirm the update
addresses the comment(s)
2. merge the PR when there are 2 (or more) positive reviews, and no
negative ones
don't merge when the 'do-not-merge' label is added to the PR
also require that the status checks (CI) has passed
3. in case there are merge conflicts, Mergify will leave a message
asking for a rebase
