[feat] Updater should handle unmanaged install modes better #4573
Description
Describe the problem
When running the updater with default settings (dialog: true), it will prompt to download & install and fail silently if running e.g. as a .deb. The biggest issue is that this is confusing:
- It offers to do something it cannot do.
- It doesn't report the failure to the user.
Describe the solution you'd like
A few options:
- unmanaged install, unmanaged updates (msi, appimage, dmg): search & prompt to install (works today)
- managed install, unmanaged updates (deb*, rpm*):
- search for updates & offer to open download link in browser (tauri.conf.json field?) or
- search for updates, download and launch the installer for the user, and let the user authenticate etc
- managed install, managed updates (mac app store & windows store?): don't search for updates (fully managed)
- N/A (dev mode): don't search for updates at all?
*: don't know if possible to tell the difference between "deb repository url" which IS managed or ad-hoc installed deb (most common today I assume). If it's not feasible, it could be best to not search at all.

Additional context
An additional issue is that we only have one url per [target, arch] tuple, which is hard to extend. E.g. linux infers appimage. This would make it tricky to add support for e.g. automatic deb downloads.
