Forces a static title to be set on the window hosting the browser. If not configured, the widow's title is set to the web page title.

It is possible for applications to bundle a fixed version of the runtime, and ship it side-by-side. For this you need to tell MSAL (so it can tell WebView2) where to find the runtime bits by setting this property. If you don't set it, MSAL will attempt to use a system-wide "evergreen" installation of the runtime." For more details see CoreWebView2Environment.CreateAsync Method.
