Update appVersion and add public images directory

Updated the appVersion in Chart.yaml from 3.0.9 to 3.0.10 to
reflect the latest version of Paperless AI. In the deployment.yaml,
added a new volume mount for a public images directory at
'/app/public/images' with a size limit of 100Mi. This change
ensures that the application has a dedicated space for public
images, which can help in organizing image storage and manage
resources more effectively. No breaking changes are introduced
with this update.
