Add a setup for releasing via tags

[kategengler]

• Also add a publish-to-branch workflow to see the built contents on a branch

@kategengler should the release readme mention how the automated publish works?

For example if I merge a pr with Breaking and then 10 minutes later merge another pr with Breaking, will that auto publish two new major versions?

[kategengler]

This is not automated publishing. A person still needs to run npx release-it to create & push the tag that will trigger CI to publish. Details are in the RELEASE.md that is added

Taking that <3 as approval to merge ;)
