Offer opportunity to update filter lists before reporting issue
Related discussion:
- https://github.com/uBlockOrigin/uBlock-issues/discussions/2582

If there exist any built-in filter list which last update time
is older than 2 hours, the "Report a filter issue" page will ask
the user to update their filter lists then verify that the issue
still exists.

Once filter lists are updated, the troubleshooting information
will reflect the change in update time.
