Update deck & luma 9.1

[xinaesthete]

Updates deck & luma versions (also change to listed allowed react versions, vague on this and maybe it should be separate).

Fixes #854 (somewhat redundantly as another PR already does this, not sure why that wasn't merged).

Background

Trying to keep up-to-date with these (in particular, I think they changed something so that gl context is made with preserveDrawingBuffer which I need, and I couldn't seem to get the right option passed through with 9.0)

Change List

• "@deck.gl/*": "~9.1.11"
• "@luma.gl/*": "~9.1.9"
• "react" to include || ^ 19.0.0 (not meaningfully tested)
• "@probe.gl/test-utils": "^4.1.0-alpha.2" (dubious about changing to an alpha, just changed things until pnpm i stopped complaining)
• remove import { createTestContext } from '@luma.gl/test-utils'; in layers test utils, as the resulting device wasn't actually being used and this import no longer exists

Checklist

• Update JSdoc types if there is any API change. (n/a)
• Make sure Avivator works as expected with your change.

Not tested with a large number of different files so far, but seems ok.

Automated tests pass (although for some reason I thought it was hanging at some point and now I don't know why it behaves any differently).
