fix: Allow disabling of webinstaller files to avoid confusion with actual installers

[devinbinnie]

This PR allows the disabling of web installer files for electron-updater when it is only expected that a full installer should be downloaded.

This prevents a potential flaw in which an attacker using a webinstaller could serve a package not authorized by the developer to the end-user with malicious code inside.

Please also add a .changeset file for this PR via pnpx changeset. Seems like it should be a major bump if we do default disableWebInstaller to true (completely fine since we're in a v23-alpha so we can include breaking changes)
