-# About:
-#
-# This is a helper script to tag and push a new release. GitHub Actions use
-# release tags to allow users to select a specific version of the action to use.
-#
-# See: https://github.com/actions/typescript-action#publishing-a-new-release
-#
-# This script will do the following:
-#
-# 1. Get the latest release tag
-# 2. Prompt the user for a new release tag
-# 3. Tag the new release
-# 4. Push the new tag to the remote
