Reset duplicate notifications from new plugins

[timur27]

Description

This issue further enhances the detection mechanism of duplicated payment methods introduced in #8384.

The current implementation lets merchants dismiss notices on the Settings page. Once dismissed, these notices no longer appear, which is expected. However, this behavior also prevents previously dismissed notices from reappearing, even when new plugins that could cause duplicate notifications are enabled. It will be helpful for merchants if the dismissed notice reappears when there's a new plugin causing duplicate payment methods enabled on a store.
