China: Number of items blocked social media sharing

Background / User story

As follow up of https://gitlab.com/eyeo/adblockplus/abpui/adblockplusui/merge_requests/409, and to complete https://gitlab.com/eyeo/adblockplus/abpui/adblockplusui/issues/485, we need to take into account UI and logic/behavior for China market. We should show to Chinese speakers both: Weibo, Facebook and Twitter, in case the user is out of Chine, as we can't know what is their location.

What to change

• Design: TBD
• Research: TBD
• Spec: https://gitlab.com/eyeo/specs/spec/merge_requests/308

Hints for testers

For Chinese locales, Weibo icon should be present in the popup, next to the Facebook and Twitter for sharing the total number of blocked ads to social media.

Hints for translators

• Ensure titles are in Chinese.
• Text for sharing on Twitter must not exceed 280 characters (incl. link and user name).

Integration notes

This is a followup issue for https://gitlab.com/eyeo/adblockplus/abpui/adblockplusui/merge_requests/409. It will require adding the new asset to link to Weibo in the adblockpluschrome repository.
