Turborepo, pnpm and tsup 🔥

[tyrauber]

This PR configures eas-monorepo-example with a turborepo build process. It also updates packages/ui to use tsup instead of builder-bob, sorry bob. And it configures the app to use pnpm.

We still need to shamefully-hoist - (Should I feel shame? Because I do.)

But, overall it’s a really nice build pipeline.

$ pnpm install --shamefully-hoist
$ pnpm build # to build the workspace with turborepo
$ pnpm managed start
$ pnpm clean # to reset everything

Feels good, man.

And sets it up the monorepo nicely for dropping in apps that need to run in parallel like an Express API, Next or Remix.

Hey @tyrauber! Awesome work. I'm amazed you went all the way through! Sorry for not replying earlier. I'm thinking of a good home for this one, because this repo is also referenced from the Expo docs, I'm trying to keep it as minimal as possible (and with the supported yarn workspaces ofc).

Maybe we could split this one out into expo-monorepo-fast or something like that, where the focus lies purely on performance. And we keep an expo-monorepo instance with as minimal things as possible, basically behave like a vanilla template.

How does that sound?

@byCedric, yeah, no worries. I got similar implementations in a few repo's including the remix-expo repo. Just sharing.

One change I would make to this repo is replace builder bob with tsup, or better yet, standard typescript compilation. I don't think there is a need for that dependency and might lead to confusion. I think writing all packages in typescript and relying on a standardized tsconfig and build process leads to best practices.

Thanks for the review.
