Update paperless-ngx chart version to 0.26.1

Changed the chart version in Chart.yaml from 0.26.3 to 0.26.1
to align with the latest stable release. This version bump was
necessary to ensure compatibility with the recent updates and
bug fixes in the application. Additionally, updated the image
tag in values.yaml to utilize the AppVersion variable instead
of a static value, allowing for easier management of
image versions in line with the chart versioning. No breaking
changes are introduced with this update.
