Extensions should be able to be upgradable in native builds

[abose]

Currently, we cannot upgrade extensions in native builds due to the Tauri asset cache. Even though Phoenix updates the extension in the disk, Turi still serves the cached old extension assets after the upgrade. This cannot be fixed at Tauri end; see https://discord.com/channels/616186924390023171/1164659580899430530

To get around this, we might have to append the extension version in the extension paths so that the cache gets invalidated on the extension update.

We did a work around to show a dialog to the user to restart phoenix as we will be moving to a new extension store any way and extension updates are extremely rare at this time.
Closing.
