davidfrickert f1f9142a3c fix: Exit docker container on any process exit (#462)
## Description
Issue described in #460

## Changes

- Edited `supervisord.conf` to exit if it detects any of the supervisored processes exiting.
- minor text fix

## Notes

Without this change (or something similar), if act_runner fails, then the container will stay up as a zombie container - it does nothing and does not restart. After this change, if act_runner fails (e.g. due to Gitea instance being down), then supervisord will exit and the container will be restarted.
