Updater (Windows) - Skip UAC task not handled

## Description

The WIX installer provides the option [enableElevatedUpdateTask](https://v2.tauri.app/reference/config/#enableelevatedupdatetask). It does however seem that this task is not honored by the updater plugin anymore.

I have tracked down the history of this feature:
- It was originally contributed by @euphbriggs in this [pull request](https://github.com/tauri-apps/tauri/pull/2155).
- It was successfully migrated to this repository in this [commit](https://github.com/tauri-apps/plugins-workspace/pull/350/files#diff-c2a8e363b77fb6a1cadb1e96c22ef3d7e85ab9b0b9037e18c836b28319c83967) for the v2 release
- It was however intentionally or accidentally removed in this [refactor](https://github.com/tauri-apps/plugins-workspace/pull/431) by @amrbashir

If this was an intentional removal it would be great to hear what the reason was @amrbashir?

For our App we're currently considering the need for silent updates for system wide installs and this feature seems to be what we need. If we do decide to go this route I might be able to contribute the restoration of this feature to the updater plugin if the removal was indeed accidental.
