templates(arc): propagate NODE_ENV to application in arc sandbox mode

[lpsinger]

Fixes #198.

Testing Strategy:

I ran npx create-remix@latest, created a new Architect project, and ran npm run dev. I opened a browser, turned on developer tools, and showed the JavaScript console. Here are screen shots before and after this patch, showing that the #198 is fixed.

@lpsinger since this PR only makes changes to templates, can you rebase on main? That way we can get this out to users without waiting for the next Remix release

Done.

I don't know how it works, do you need to cherry-pick this onto the dev branch now?

Nope, dev can have stale templates. When we do a release we'll sync up dev and main, which will pick up the changes in main. No action needed on your part.
