Release the live environment under provisional subdomain

The development branch dev currently acts as main branch of the repository.

Commits to dev trigger a pipeline to build and deploy nightly.ecobytes.net.

Commits to next trigger a pipeline to build and deploy next.ecobytes.net.

These pipelines can also be triggered by a webhook initiated by changes in the content backends at:

• nightly.content.ecobytes.net/
• next.content.ecobytes.net/

We need similar facilities for a staging-live environment, that sets in place all tooling for the final switch.

–

• Commits to main trigger a pipeline to build and deploy live.ecobytes.net/.
• Changes in content collections at content.ecobytes.net/ trigger a rebuild, too.
