fix(kyber-linux): install WebView2 via standalone installer, not bootstrapper

Browse Source 
The Evergreen bootstrapper (linkid=2124703) requires a second download from
inside the Wine process, which fails in Proton. Switch to the standalone
offline installer (linkid=2135547, ~150 MB) which installs without any
Wine-internal network calls.

Also prefer winetricks if installed — it uses a local cache, handles the
WINEPREFIX env correctly, and is the most reliable method. Fall back to
the standalone download if winetricks is not available.
