Remember per-add-on "Create backup" toggle preference across updates

[Jerry0022]

Describe the feature

Problem

When updating an add-on, the "Create backup before updating" toggle always resets to its default (enabled) on every update dialog. Users who intentionally disable this toggle must re-disable it every single time they update any add-on.

Proposed solution

Persist the backup toggle preference per add-on. When the update dialog opens, restore the last-used setting for that specific add-on instead of always defaulting to enabled.

Alternatives considered

• A global default setting for all add-on updates — simpler but less flexible than per-add-on preference.
• No change — users continue to toggle manually on every update.

Use cases

I maintain a custom add-on that updates frequently during development. Every update, I have to manually disable the backup toggle because I don't need backups for minor iterations. With multiple add-ons updating regularly, this becomes a repetitive task that adds unnecessary friction to the update workflow.
Not only for developping it but as well as normal user I face the same issue.

Current workarounds

Manually toggling "Create backup" off on every single add-on update. There is no way to persist this preference or set a default.

Anything else?
