Update dependencies

[simolus3]

This adopts pnpm version 10 and switches to corepack to install it in GH actions instead of using an explicit setup step. That then allows using the package cache built in to actions/setup-node.

Updating to pnpm 10 resulted in new audit errors, I assume because the tool became more sensitive in that version? To fix those (and to generally ensure the demos are up-to-date), I've migrated all our dependencies to use version catalogs. This ensures we're using the latest dependencies in all workspace packages (some of the demos were using exact version dependencies for ancient packages, yikes).

Given the major updates, I'll manually verify that each demo continues to work

This is the first time I see the version catalogs feature - looks really useful for monorepos like this.
