📚 Description

This adds support for --edge and --publish flags when passed on CI to do something like:

It will automatically enable provenance if running in GitHub Actions, and will bump package version appropriately.

Thanks 🚀 I have quickly iterated to make some refactors, mainly to introduce this feature as (more generic) name/version suffix options to internal utils. Also introducing feature (CLI shortcut) as (more known) --canary with the ability to set --canary edge to be more similar to Nuxt/UnJS edge channels via one command.

Looks great! ❤️
