SilentMashiko's updated glyph info

[SilentMashiko]

I've added 1 extra way to get my glyph recently, so I'd like to have it added in here, since current info is outdated.

It should be as follows:

• YouTube paid sub (channel membership) or VKontakte paid sub (via VK Donut)
• Level 20 on Discord server via MEE6 bot
• Giveaways.
