create-release-and-publish-packages.yml

# This GitHub Action workflow is triggered by a git tag being pushed where the tag name starts with 'v'.
# The workflow runs two jobs:
# - create a GitHub Release from the git tag, using RELEASE-NOTES-NEXT.md as the relese notes
# - build a package using Maven and then publish it to GitHub packages
on:
  push:
    # Sequence of patterns matched against refs/tags
    tags:
      - 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10

# (Previously, we expected the GitHub Release to be created manually, which would then trigger the `publish` job.)
