Update build script to use remix vite:build and update Readme with Vercel hosting instructions for Remix with Vite

[jeffsee55]

Vercel recently shipped a Remix Vite plugin that no longer requires a forked version of Remix. The package also exports platform-specific utilities that may need to be imported at runtime, detailed in the docs link above. This PR updates the README for the Vercel-specific instructions.

It also modifies the build script, I noticed that the build command was reverted from remix vite:build here, I'm not sure on the specifics of why that was necessary but the Vercel preset won't work without the remix vite:build command as far as I know. If there's a reason the remix command can't be used then this PR should just be closed as it won't help.

Hi there @jeffsee55 👋

Thank you for this! If we can eliminate special cases for deployment that is great!

I was wondering if you happened to test deploying one of our app templates?
We have just gotten reports of Vercel deploys now failing 😞 , we are just trying to determine if this is related to our recent release, the changes to Vercels deployment or a combination.

Thanks @lizkenyon, I did get this to deploy successfully with an existing template, I'm not sure exactly what you mean by one of your app templates.

I don't think this relates to the Vercel deploys which are failing, but I did want to highlight again that the build script that I changed in this PR was intentionally rolled back in a previous PR, presumably for good reason #564 but I couldn't gather enough info from the PR to know why.

Hi @jeffsee55

Sorry by one of our templates, I was referring to the code in this repository.

Yes, we should be good to change the build script to what you have. If you are able to sign the CLA, we will test this on our side and get this merged! Thanks again!

Thanks @lizkenyon, signed! I also resolved a merge conflict that was created from #358. I think the area that was updated in that PR was a typo (extra space) so went ahead and continued to delete that sentence

Hey @jeffsee55

This is slightly unrelated, but it seems new deploys of Shopify App Remix templates are now failing.

We tracked this down to our use ofimport assertions in one of our libraries.

I created a discussion on the Vercel github, and I was wondering if you could help getting some eyes on this by the right person?

Thanks @lizkenyon, we'll take a look!
