fix(Dockerfile.rootless): revert to default path for app.ini

Browse source 
The current path of the `$GITEA_APP_INI` configuration file makes the
forgejo application reset every time the container is restarted, unless
a specific volume for this file is created. Consider the following:

* This quirk is not documented
* All configuration data resides in `/var/lib/gitea`
* The custom configuration path defaults to `/var/lib/gitea/custom/conf`
  (see `forgejo -h`)
* Containers mounting the volume `-v /foo/bar:/var/lib/gitea` already
  have this file available to modify. Another volume shouldn't be
  required
* Containers using named volumes can use `docker cp` to modify the file
  inside the volume, if desired

For these reasons, it makes more sense to use the default path for
`$GITEA_APP_INI` rather than require users to create a dedicated volume
for the file. Revert it back to its default while maintaining backwards
compatibility (users can update by simply moving the file to the new
path).

Reverted the rootless container image path in `GITEA_APP_INI` from
`/etc/gitea/app.ini` to its default value of
`/var/lib/gitea/custom/conf/app.ini`. This allows container users to not have
to mount two separate volumes (one for the configuration data and one for the
configuration `.ini` file). A warning is issued for users with the legacy
configuration on how to update to the new path.
