virtualbox-with-extension-pack-np: Fix autoupdate for ext-pack version

Add VirtualBox extension pack to autoupdate URLs, to prevent mismatch
between base installer and extension pack versions. Scoop supports
autoupdate URL collections with: [ScoopInstaller/Scoop#3518](ScoopInstaller/Scoop#3518).

Related to #238.
