getWorkspaceOwnerData for dynamic parameters is supposed to mirror how provisionerd injects user state.

See:

• coder/coderd/provisionerdserver/provisionerdserver.go

  Line 641 in 5816455

  allUserRoles, err := s.Database.GetAuthorizationUserRoles(ctx, owner.ID)

• coder/coderd/provisionerdserver/provisionerdserver.go

  Lines 697 to 701 in 5816455

  	WorkspaceName: workspace.Name,
  	WorkspaceOwner: owner.Username,
  	WorkspaceOwnerEmail: owner.Email,
  	WorkspaceOwnerName: owner.Name,
  	WorkspaceOwnerGroups: ownerGroupNames,

This should ideally be the exact same method/function
