SERVER-125672 gated the coordinator’s legacy reshardingFields writes on the no-refresh path because participants learn about resharding through explicit commands instead of shard-version refreshes on config.collections. However, coordinator state transitions still go through writeStateTransitionAndCatalogUpdatesThenBumpCollectionPlacementVersions, which bumps placement versions for the source namespace and the temp resharding namespace while running the metadata updates. 

We should skip these placement version bumps for non-committing coordinator transitions when the config.collections writes are effectively no-ops to avoid any unnecessary refreshes.
