func PinnedBuildIdSearchAttribute 

func PinnedBuildIdSearchAttribute(version string) string

PinnedBuildIdSearchAttribute creates the pinned search attribute for the BuildIds list, used as a visibility optimization. For pinned workflows using WorkerDeployment APIs (ms.GetEffectiveVersioningBehavior() == PINNED && ms.executionInfo.VersioningInfo.Version != ""), this will be `pinned:<version>`. The version used will be the override version if set, or the versioningInfo.Version.

If deprecated Deployment-based APIs are in use and the workflow is pinned, `pinned:<deployment_series_name>:<deployment_build_id>` will. The values used will be the override deployment_series and build_id if set, or versioningInfo.Deployment.

If the workflow becomes unpinned or unversioned, this entry will be removed from that list.
