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

See:

• coder/coderd/provisionerdserver/provisionerdserver.go

  Line 641 in5816455

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

• coder/coderd/provisionerdserver/provisionerdserver.go

  Lines 697 to 701 in5816455

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

This should ideally be the exact same method/function
