Missing DISCORD_NOTIFY lines for XBox in dotenv

[Jack1424]

I'm not sure if the lines work, but they are missing from the dotenv-example file. I double-checked the repo to be sure.

I added:

DISCORD_NOTIFY_GROUP_XBOXSX=
DISCORDNOTIFY_GROUP_XBOXS=

to my dotenv file, but I don't know if they work.

They do work! Good catch, they didn't get added to the example. I'll add now.

Thanks!
