fix(msi): MSI fails to install when deployed machine-wide via GPO

Disable advertised shortcuts, since MSIs with advertised Start Menu shortcuts that have a
Shortcut Property fail to install when deployed machine-wide via GPO, but work fine in all
other contexts. This might be a bug in Windows, or a misdiagnosis; see electron-userland#6508 for more details.

Closes electron-userland#6508
BREAKING CHANGE: Admins using advertisement must apply an MST to re-enable it. See electron-userland#6508.
