Add a comment warning developers to push pv tags
The following comment has been added to versions.txt:
While the goal is to be consistent with a SHA on ParaView's main fork, CMB frequently uses a custom fork of ParaView in order to maintain functionality while updating the connections between the two projects. When this happens, it is critical that the forked ParaView also push ParaView's tags to the fork, since this is how ParaView determines its version (and, resultantly, how it names its libraries).
To push ParaView's tags:
$ cd <path-to-sb-build-tree>/superbuild/paraview/src
$ git remote add kitware https://gitlab.kitware.com/paraview/paraview.git
$ git fetch --tags kitware
$ git push --tags origin
