add open-next deployment github workflow

[dario-piotrowicz]

Description

The changes here add a workflow that deploys the OpenNext version (deployed at https://node-test.org) of the site on every push to main, so that we can make sure that such version is always up to date with the official version.

Validation

This will be validated once merged (and merging it is very low risk)
