Improves ADK FWLink resolution for robustness

Refactors the ADK URL retrieval logic to let `Invoke-WebRequest` handle the forward link redirection directly. This approach is more reliable than manually parsing the redirect response.

Adds a try/catch block to provide better error handling and logging during the URL resolution process.
