Add Get-ADKURL and Install-ADK functions

This commit introduces two new functions, Get-ADKURL and Install-ADK, to facilitate the retrieval and installation of the Windows Assessment and Deployment Kit (ADK) components.

The Get-ADKURL function retrieves the download URL for the specified ADK option (either "Windows ADK" or "WinPE Add-on") from the official Microsoft documentation page. It utilizes web scraping to extract the URL dynamically.

The Install-ADK function downloads the specified ADK component from the obtained URL and installs it silently on the system. It handles errors gracefully and cleans up the temporary installation file after completion.

These functions enhance the automation capabilities of the project by simplifying the process of acquiring and installing ADK components required for Windows deployment and assessment tasks.
