ci(mergify): Re-request devs review until required approvals are met (#444)

The request-review rule stopped requesting @devs after the first approval (#approved-reviews-by=0), yet the Approval merge protection requires two. A pull request would silently stall after review #1 with no reviewer requested for review #2.

Match the monorepo behavior: keep re-requesting @devs while below the two-approval requirement (#approved-reviews-by < 2). When a dev reviews, GitHub drops the team request and Mergify automatically re-adds it until the merge gate is satisfied.
