Update paperless-ngx chart version to 0.25.0

The version number for the paperless-ngx chart has been
downgraded from 0.25.1 to 0.25.0 in the Chart.yaml file.
This change may have been necessary due to issues or bugs
identified in the 0.25.1 release that require reverting to
a more stable version. The appVersion remains unchanged at
2.20.0, and the kubeVersion requirement is still set to
"">=1.28.0-0".

No breaking changes are introduced with this version
rollback, but users should ensure that their deployments
are compatible with the features and functionality provided
in version 0.25.0.
