ci: add release.yml

[msimerson]

This PR does:

• ci(release): generate a GitHub release and NPM publish when ALL of the following criteria are met:
  • a PR has merged against master/main
  • the build tests pass
  • the version in package.json has increased

In order for NPM publishing to work, Trusted Publishing has to be set up for the NPM package. @lsongdev, that requires you to make the following edits on the package settings page. The following settings for OIDC / Trusted Publisher need to be:

• Publisher: Github Actions
• Org: lsongdev
• Repository: node-dns
• Workflow filename: release.yml
• Allowed actions: Allow npm publish

I have set it up package publishing on npmjs.

thanks! publish is almost automated, but I forgot to set up the NPM publishing step in release.yml. Time to go fix that.
