Using pnpm, route content doesn't show

[itsMapleLeaf]

Reproduction steps:

1. Install pnpm
2. Set up a new remix project pnpm init remix, say "no" to automatic install
3. Install dependencies: pnpm install
4. Run the dev server: pnpm run dev

(technically, only 3. needs to use pnpm over npm, but consistency 🤷)

This is what shows, just the footer, no route content

As suggested with some help from @JNaftali, I tried to change the "remix" imports to "@remix-run/node" and "@remix-run/react" where appropriate, but still ran into the same issue.

I think the solution might be for the remix package to declare hard dependencies on the react and node packages

Not sure if this is relevant, but a common issue is that pnpm doesn't implicitly run post and pre scripts. Maybe there's a postinstall hook that isn't running? See https://pnpm.io/cli/run#differences-with-npm-run

Methinks this be a duplicate of #154.
