This commit updates the version of the paperless-ngx Helm chart
from 0.25.1 to 0.25.2. This change is necessary to ensure that
users are able to take advantage of the latest features,
bug fixes, and improvements provided in the new release.
The appVersion remains at 2.20.0, and the kubeVersion
requirement is maintained at ">=1.28.0-0". No breaking changes
are introduced with this version bump.
