fix: Remove obsolete version attribute and simplify direnv

- Removed 'version: 3.8' from compose.yml (obsolete in Compose V2)
- Removed redundant moodle-help function from .envrc
- Simplified to just point users to 'make help'

This eliminates the Docker Compose warning about obsolete version attribute.
