Release 2.5.0

• Added update to the public API for NavigationFlow, as this is required for some use cases where the flow needs to be updated after changes in external state which may affect the logic of the flow. This function was previously named next, and removed from the public API in 2.4.0.
• Moved NavigationContext.getViewModel and requireViewModel extensions to the dev.enro.viewmodel package.
• Added NavigationResultScope<Result, Key> as a receiver for all registerForNavigationResult calls, to allow for more advanced handling of results and inspection of the instruction and navigation key that was used to open the result request.
