docs: Add documentation for PRESET environment variable

- Add PRESET to the environment variables table
- Include detailed explanation of available preset values
- Add example showing how to use PRESET when generating a new map
- Document that PRESET is optional and only used with GENERATE_NEW_SAVE=true

Fixes #571
