Add new function CapacitorUpdater.GetFailedUpdate()

[co-dax]

Add a function to get the last failed update.

There is alerady a related functionality implemented with the event addListener('updateFailed', ...) but the limitation we are having with it is that we need to get the failed update info at a specific line of code to determine if we the last update has been successful and bootstrap the application based on that info and this is not possible using the even addListener('updateFailed', ...) as it will fire at whatever point in time during the application start.

Here is the list fo this functionality implemented using the event https://github.com/Cap-go/capacitor-updater?tab=readme-ov-file#addlistenerupdatefailed-
