Enhancement Request: Adding Customization Options to WebScrapper Tool

Currently, the WebScrapper tool offers a solid foundation for web scraping tasks. However, to better suit diverse use cases and enhance its flexibility, I propose the addition of more customization options.

Proposed Customization Options:

User-defined Selectors: Allow users to define their own CSS or XPath selectors for targeting specific elements on web pages. This would enable more granular control over the scraping process and accommodate websites with complex structures.

Look for the web scraper module in the codebase, likely under a directory like `src/web_scraper` or `src/tools`. Examine the current scraping logic to understand how selectors are used. The goal is to modify the API to accept user-defined CSS or XPath selectors, ensuring the change integrates with the existing tool configuration and error handling. Testing will involve updating any existing tests for the scraper and writing new ones for the customization feature.
