WIP: hoist devDependencies and migrate to workspaces + rollup

[ThisIsMissEm]

This is a highly experimental branch, where in I'm attempting to address some long standing issues with how we build the code in this repo. The commits are not minimal, there's a lot of cruft that needs to be cleaned up, but it's a first working version.

One note for Next.js: If you're using @inrupt/solid-ui-react and encounter an error when loading the SessionProvider (or other components), and the error is about window being undefined, well, it turns out that's kinda a next.js quirk that webpack was silently allowing to work somehow. We do need to "fix" the SDK to not make direct use of the window global object, but that's additional work that I'm trying to keep out of scope.

If you wanna test in next.js you'll need to do the following instead of just import { SessionProvider } from "@inrupt/solid-ui-react":

const SessionProvider = dynamic(
  () => import("@inrupt/solid-ui-react").then((mod) => mod.SessionProvider),
  {
    ssr: false,
  }
);

Additionally, there's some package json changes needed to properly tie it all together:

    // New dependency versions
    "@inrupt/solid-client-authn-browser": "1.11.9-alpha.5",
    "@inrupt/solid-ui-react": "^2.8.0-0795c00b",

  // Overriding the version of authn-browser in solid-ui-react:
"overrides": {
    "@inrupt/solid-ui-react@^2.8.0-0795c00b": {
      "@inrupt/solid-client-authn-core": "^1.11.9-alpha.5",
      "@inrupt/solid-client-authn-browser": "^1.11.9-alpha.5"
    }
  }

Webpack is only used for the example apps now, but we can and probably should migrate to something else there (swc, next, rollup, etc)

this is needed until we publish @inrupt/[email protected], as v0.4.0 / v0.4.1 do not use Jest 27

[ThisIsMissEm]

pretty sure this was a bug

@NSeydoux let's figure out a plan for the work that's been done here, most is already done elsewhere now, so really there's just the webpack -> rollup migration left.
