[Bug]: Helm Chart Volume Mount Root Permissions

[B1ue-W01f]

Where is the problem occurring?

I encountered the problem while interacting with the server (Backend)

What browsers are you seeing the problem on?

Chrome

Current behaviour

Current helm chart results in the 'project-background-images' and 'user-avatars' directories being mounted as root, this prevents uploads from working with a permission denied log message.

Desired behaviour

Default values.yaml file should initiate a working application.

I believe - though could be wrong - the below entries should be made in the values.yaml file, these can be further customised by a user if required but would prevent standing up a none working app.

podSecurityContext:
  fsGroup: 1000

Steps to reproduce

Follow guidance here:

Leave values.yaml as default.

Other information

Id be happy to make a pull request if the proposed solution appears correct to others.
