Subject: [PATCH] add an adhoc chart-releaser that is triggered by the
 `/release-adhoc` issue comment

This allows for releasing (in an adhoc fashion) from a branch. Unfortunately the behavior and how this will work for non-devel releases is not super well-defined. If chart-releaser adds support for filtering to only certain releases, that would be helpful to make this safer: https://github.com/helm/chart-releaser/issues/196

In particular, it is most concerning if chart A moves to `--devel` version on the `dev` branch, chart B moves to a newer version on `main`, and then CI runs. It would also be concerning if chart A or chart B move to a newer version on a branch and then publish a "non-devel" version from the branch.
