Harvest docker compose workflow should not rename prometheus/grafana volumes during upgrade

[rahulguptajss]

As reported on discord

• [x] Update code to make volume names same
• [ ] Document how to upgrade from previous releases where volume names are prefixed with dir name.

Changelog needs to mention that when upgrading to 22.11 you must regenerate your Docker compose files by rerunning bin/harvest generate docker full --output harvest-compose.yml

Then we need to document how to upgrade from earlier versions of Harvest to later ones when using the docker compose workflow.
