Bug description

Running vtk.js on the backend doesn't work without modifying the package.json.

(Maybe this is a feature request?)

Steps to reproduce

Try installing @kitware/vtk.js on node when using ESM. The package is incorrectly loaded, and it will run properly when "type": "module" is added.

Detailed Behavior

No response

Expected Behavior

It works OOTB in node. Is there any other issue that would be caused by adding "type": "module" to the package.json?

Environment

• vtk.js version: master
• node.js 18+ (but probably before also).
