Update vtk.js to 29.4.6

[PaulHax]

Replaces vtk DistanceWidget with LineWidget

Couple TODOs

• [x] When running test localy (npm run test:debug) getting a RangeError: model.size is not a multiple of model.numberOfComponents in impjoy tests when trying to call itkVtkViewer.utils.ndarrayToPointSet`. Due to this? https://github.com/Kitware/vtk-js/commit/3cc3abb871cabb79831d26bb268990549ef6ca59
• [x] Perhaps unrelated error being unable to create WebGL in headless docker container around test 79. Error occus even with using vtk.js 26.9.15. So cause is probably due to updated Chrome. Happens with Puppeteer 13.1.0 which is Chrome 98.
