Fix duplicate Reviewed-by trailers (#24796)
Enable deduplication of unofficial reviews. When pull requests are
configured to include all approvers, not just official ones, in the
default merge messages it was possible to generate duplicated
Reviewed-by lines for a single person. Add an option to find only
distinct reviews for a given query.

fixes #24795
