vtk socks setup fails with Ruby 3.3.3

[sarahwcodes]

First time running vtk socks setup was successful, but after my key was approved, I re-ran it as instructed and encountered an error using rbenv with ruby 3.3.3:

I solved it by uninstalling the vtk gem, running rbenv install 3.1.6, resetting the local version (rbenv local 3.1.6) before running gem install vtk again. When I ran vtk socks setup for the second time, it succeeded without any errors.
