Routinely clear out or expire stale creator info from `publisher_info_db` so that browser fetches fresh creator info upon next visit

Description

For example, if a Twitter creator changes their name, and a user had already visited that Twitter account prior to the name change, it will retain the old string and show the old name string in the Rewards panel. The name is essentially cached with no expiration.

Solution

Clear out stale creator entries from publisher_info_db periodically so that the browser fetches new information next time the user visits the creator’s page.

QA steps to verify:

1. In Brave, navigate to a twitter page you own, e.g. twitter.com/supergood
2. Open the Rewards panel and note supergood shown in the panel
3. In twitter settings (account settings) change your name (handle) to something else, e.g. extragood
4. In Brave, navigate to the page twitter.com/extragood Before the fix:
5. Open the Rewards panel and note supergood is still shown in the panel With the fix:
6. Open the Rewards panel and note extragood is now shown in the panel
