  release_tag:
    description: >-
      If supplied, this tag will be used as an "alias tag" that is continually
      updated and moved to point to the most recent Helm Chart release tag.
      Eg. If you have app-1.2.3 and you release app-1.2.4, the "alias tag"
      will be moved from app-1.2.3 to app 1.2.4. This is useful for
      maintaining a "stable" or "production" pointer tag for CI tooling for
      developers.

      Note: Make absolutely sure that if you have multiple charts in your
      repository that you customize this to include the chart name -
      otherwise this value will be moved around between charts.
