Fix issues in `volumeMounts`

[lindhe]

Description

This PR does three things:

1. Reverts an earlier commit that removed subPath from the volumeMounts.
2. Adds subPath to the worker pod, where it was missing.
3. Fixes a typo for the volume name.

The reverted commit tried to fix an issue where we got duplicate directory names (data/data/), but the issue was not that web used subPath but actually that worker did not.
