Removes Now.sh pipeline

[supernova-at]

Description

We have AWS deploying on a per-PR basis, so we no longer need the Now.sh pipeline. Our https://veniapwa.com demo site has been redirected to the AWS deployment of master.

Related Issue

Closes #1546.

Verification Steps

1. Verify that now.sh-related code doesn't appear anywhere in the codebase
2. Verify that the Now GitHub integration no longer appears on PRs

Screenshots / Screen Captures (if appropriate)

Checklist

• I have updated the documentation accordingly, if necessary.
• I have added tests to cover my changes, if necessary.

• Remove the Magento team from Now.sh website
• @mmansoor-magento to remove Now GitHub App from magento organization

Had an offline conversation with @zetlen about not removing Now completely because it does still provide some value because it runs in a lambda and it will keep us honest about the application not being stateful.

We have therefore repurposed this ticket to update our Now installation.

#1595 is in! This issue is unblocked and has been updated.

Good news and bad news though:

Good News:

The deployments are working. If you hit https://pwa-studio.supernova-at.now.sh/ you do see Venia.

Bad News:

The app is repeatedly attempting to hit /rest/V1/guest-carts at the deployment URL (ex: https://pwa-studio.supernova-at.now.sh/rest/V1/guest-carts), not the MAGENTO_BACKEND_URL.

We have followed the documentation to provide environment variables at both build and run time via our now.json file.

I'm stuck 😢

[zetlen]

That should work though. UPWARD ought to properly proxy that request to MAGENTO_BACKEND_URL. But you can also reproduce that proxying behavior before it hits upward-js. I think you might need to add the routes section of now.json back. Without that, I'm not sure how we're making every single request resolve to index.html!

Update: following a team meeting this PR has been repurposed back to removing Now.sh entirely.

If / when we want a deployment target other than the Magento Cloud we can add it back.
