Helm Chart Should Use a Dynamically Allocated Volume for metacat-themes #2740
Description
Describe the feature you'd like
The helm chart should automatically use a dynamically allocated volume for metacat-themes, instead of requiring the user to manually set up a volume, PVC and PV for this purpose.
Additional context
Since the metacatui theme updates are now automated, we no longer need access to the files to do manual updates from git. Setup currently involves manual creation of a Persistent Volume, which requires admin access. Admin access is not available to most developers in our group, and may not be available to non-NCEAS orgs installing Metacatui on k8s clusters.
Changing the chart to use a dynamically allocated volume will solve this access issue, and will also mean fewer manual steps on first install, less cognitive load when administering files on the ceph mount, and automatic creation of backups instead of needing to ping Nick.
