Provide a description of requested docs changes

After adjusting the file size limits in the .env file, uploads still failed with errors. The issue was resolved only after modifying the NGINX_CLIENT_MAX_BODY_SIZE configuration.

Recommendation:
The "Environment Variables Explanation" documentation should explicitly note that in addition to the following parameters affecting file upload limits:
UPLOAD_FILE_SIZE_LIMIT
UPLOAD_IMAGE_FILE_SIZE_LIMIT
UPLOAD_VIDEO_FILE_SIZE_LIMIT
UPLOAD_AUDIO_FILE_SIZE_LIMIT
WORKFLOW_FILE_UPLOAD_LIMIT

the NGINX_CLIENT_MAX_BODY_SIZE must also be adjusted accordingly. Failure to update this Nginx parameter may result in persistent upload errors, even if other limits are correctly configured.
