fix: jaeger traces not persisted across container restarts (#82)

Closes: WORLD-1208

## Overview

Previously the Jaeger container only stores the spans in memory, which
is lost when the container is restarted. This PR fixes this by
[configuring Jaeger to use
Badger](https://www.jaegertracing.io/docs/1.62/deployment/#span-storage-backends)
as the span storage engine with a Docker volume.

## Brief Changelog

- Updated the Jaeger container config to use badger

## Testing and Verifying

Manually tested and verified.
