category-scholar-cn: add medalink.cn (#3091)

Removed 'include:habr' from the category-ru file.

Reasons:

1) habr.com isn't affiliated with Russia directly (even though the habr.com IS hosted in Russia, it's cdn domain - habrastorage.org is hosted in Estonia)
2) the site itself contains a lot of geoblocked articles which can't be accessed without a foreign proxy - so it being in category-ru can lead to routing mishaps in cases such as routing category-ru sites to DIRECT on the client
