Bump vtkjs

[bnmajor]

and set rendering backend to WebGL

LGTM! @bnmajor thank you!

@PaulHax is going to review / merge.

Good stuff.

Was getting a structuredClone not defined error after npm run test:debug. Upgrading puppateer to "puppeteer": "^20.2.0", upgrades the Chrome version used in the test and it passes.

@bnmajor Can you bump puppeteer and and push?

Looks like there is a bug in VTK.js after changing the volume blend mode. Kitware/vtk-js#2830
I'ed vote to not hold this PR for that fix.

Thanks @PaulHax! Puppeteer has been bumped

[PaulHax]

Gaw. Another ask. CI test job is failing at the same test as npm run debug with the old puppeteer (just after 41 reset cropping planes.) Suspect that is because the Chrome version in the test docker is old.

Can we avoid increasing the vtk.js version and just specify WebGL and does that fix the issue?

@PaulHax We can skip the vtk.js bump but it doesn't look like it fixes anything - my local tests are still failing here with the following:

caught (in promise) TypeError: Cannot create proxy with a non-object as target or handler
    at publicAPI.get3DContext (index.js:287:12)
    at publicAPI.initialize (index.js:170:33)

    at publicAPI.render (index.js:899:7)
    at publicAPI.initialize (index.js:148:15)

Looks like model.defaultToWebgl2 and webgl2Supported return true but model.canvas.getContext('webgl2'/'webgl'/'experimental-webgl', options) are all returning null. FWIW this is the same error I am getting with the version bump.

[PaulHax]

OK, thanks for checking.

looks like adding a puppeteer config file actually gets the CI tests running. But they failing for the usual mysterious reasons. I am looking into it.
