Use pnpm catalog feature for shared dependencies

[myieye]

I took the opportunity to peruse pnpm's changelog and found this handy new feature to prevent modules in a monorepo from using different versions of dependencies. For lots of dependencies it doesn't matter that much, but for some it does (e.g. vite and svelte) and consistency is nice.

In an intro video it was suggested to put everything in a catalog by default. But, the current caveat of catalogs is that they're not currently supported by pnpm update. Personally, I think we can live with that for the time being.

pnpm outdated works, which is something.
