Replace "EasyList China" with "AdGuard Chinese"

As discussed internally with list maintainers:

- EasyList China doesn't leverage uBO's extended
  filter syntax

- EasyList China's home page is no longer available
  to the public

Additionally, "CJX's EasyList Lite" has been removed
from stock lists, as the list hosted on GitHub is no
longer updated, and "AdGuard Chinese" is the official
list to enable to address all filter issues for
Chinese sites.
