♻️ Refactored subgraph URL generation

- Introduced a new function to generate subgraph URLs
- Added error handling for fetching data from published subgraphs, with fallback to hosted ones
- Updated the use of this function across multiple files
- Included the ability to specify a publishedSubgraphUrl in chain configuration
- Bumped up the production version of the subgraph in config file

- Replaced the direct environment variable access for fetching the Subgraph URL with a function call to `getConfigByChain`.
- This change enhances code maintainability and readability by centralizing configuration data retrieval.
