Add a troubleshooting file

Current Behavior

There's some issues that may arise during setup that are separate from EpubPress.

Examples:

• Some versions of docker-compose not understanding version: 3.
• docker-compose needing to be run with sudo in linux.
• The chrome extension failing because of a misconfigured url.

Expected Behavior

There should exist some form of TROUBLESHOOTING.md to document the fixes to these issues.
