### Description of the change

Introducing use of the `tpl` function into _"gitea.actions.local_root_url"_ (in `_helpers.tpl`) so templating into the `giteaRootURL` parameter can be interpreted.
Hence, it will permit the use of values already set in other parameters.

### Benefits

To allow in an umbrella chart referencing to other values for setting the Gitea Root URL
