Bump version to 0.4.0 and clean up deployment.yaml

This commit updates the version of the Helm chart for Paperless AI from
0.3.0 to 0.4.0 to reflect the latest changes and improvements.

Additionally, unnecessary resource allocations in the
deployment.yaml file have been removed, particularly
the commented-out section related to resources. This
cleanup enhances readability and maintainability of the
chart's deployment configuration.

No breaking changes were introduced, but it simplifies the
environment variable section to improve clarity.
