+# When that tag is pushed it causes this action to run, which:
+#   * Ensures the gem's version (via version.rb) matches the pushed tag before doing anything.
+#   * Builds the gem.
+#   * Creates a draft release in GitHub with:
+#      * The built gem attached.
+#      * The relevant lines from the changelog in the description.
+#      * Named the same as the tag.
+#   * Publishes the gem to GitHub Package Registry.
