Fix final step of Windows auto-update

[timtmok]

Release Notes

I've got a wiki update to describe the entire update process that is WIP: https://github.com/posit-dev/positron-wiki/tree/auto-updates

It describes the steps of the auto-update in detail for Windows that explains what the installer does to update Positron.

Add missing argument to inno_updater execution. It expects 3 arguments (exe path of existing installation, lock file status, and a string for the log). See https://github.com/microsoft/inno-updater/blob/3fc01e98dadd9b41fb8073f769fe0756a6f94cf9/src/main.rs#L546 (note that it does check for 4 but the first arg is inno_updater.exe)

Without the last argument, inno_updater.exe exits without replacing the existing install with the updated one.

QA Notes

This change is required so that the auto-update will complete successfully. Otherwise, the old installation will remain with the updated one located in the <existing Positron path>\_\ directory.
