[vtk-developers] Approving a gitlab topic

[Bill Lorensen]

To approve a gitlab topic I do?

Acked-by: me

Why not?

Approved-by: me

The latter seems more descriptive.

 I currently contribute to 3 open source projects, vtk(gitlab),
itk(gerrit) and slicer(github). They each have their own workflow. I
also have several of my own projects that uses github. I contribute to
these projects in spurts.
