Configure searxng with language param set to auto and add "safesearch": 1 (moderate) for safer web results.

- The check for private IP addresses often did not yield the expected results, especially with errors like: `[Errno -2] Name or service not known`.
- Removed the check for private IP addresses in the URL validation process.
- Simplified the `validate_url` function to focus on validating the URL format and checking the existence of the URL using a HEAD request.

To address the unresolved issue in the LangChain library where a single URL error disrupts the data loading process, the lazy_load method in the WebBaseLoader class has been modified. The enhanced method now handles exceptions appropriately, logging errors and continuing with the remaining URLs.
