Added a configuration option @theme_plugin_weather_location to set a specific location (e.g., city, country) for weather instead of using IP-based detection.
Updated weather.sh to handle the new configuration, including fallback to IP-based location if the option is not set.
Documented the new configuration in the README with examples for city and ZIP code usage.
Performed minor cleanup in the README for consistency and clarity.
