<span class="doccomment">/// The `scrape` method automates web scraping by taking a URL as input and returning the webpage's HTML content. Initially, it checks for Chrome's installation, installing the latest version if necessary, to ensure a modern browser environment is available. The method uses Chrome in headless mode to efficiently load and scrape the webpage, including dynamically generated content. This process is fully automated, providing an easy and resource-efficient way to obtain the complete HTML source code of a webpage for further processing.
