change vk.com from BROKEN to PREPARATION

I have verified it, it works. I can receive emails.

But their FAQ still states that vk.com can't work with other email clients: https://help.vk.mail.ru/vkmail/questions/client Maybe they just haven't updated it yet? Or maybe they're just testing and might disable it again, as it once happened: https://vk.com/wall-104054395_14970?w=wall-104054395_14970_r15160

• [ ] Maybe it's worth waiting a bit, at least before the next DC release to see if it breaks again. Ping me and I'll test.
