fix: Include GoogleSearchCrawler script.js in package distribution

Fixes #1711

The GoogleSearchCrawler's script.js file was not included in the package
distribution, causing FileNotFoundError when using the crawler.

Added crawl4ai/crawlers/google_search/*.js to setuptools package-data
in pyproject.toml to ensure the JavaScript file is bundled with the package.
