Addon Update Notifications

Dear Devs,
I had the following idea.
Concept: Notifing the user when a new version of the addon is available.

This would work though somesort of Pop up message.
"The Addon:{AddonName} has a new version available. Currently version: {currentVersion} is used version:{newestVersion} is Available."

Then have two Buttons:
Don't show Again -> Does not show until the next version is relased
released
Update now -> Opens the addon Manger and installs the Update

Best Regards

Start by reading the Addon Manager's existing update and installation entry points, since the issue provides no file or test names. Define the notification flow around detecting a newer addon version, the “Don't show Again” reset behavior, and the “Update now” action; done means these interactions are specified and work consistently.
