Subject: [PATCH] Add FetchGoldRates job to retrieve and store gold rates

- Introduced a new job class `FetchGoldRates` to handle the fetching of gold rates from an external source.
- Implemented data extraction using DOM parsing to retrieve relevant gold rate information.
- Utilized `NumberFormatter` for consistent number formatting of the fetched values.
- Stored the processed gold rates in a JSON file for easy access and further processing.
- Enhanced the maintainability of the code by organizing the fetching logic and data handling.

This commit establishes a foundation for integrating gold rate data into the application.
