[feature] Fix switching light/dark theme in Linux

[haael]

Original Discord uses broken way to check light/dark system theme in Linux, as described here:

https://old.reddit.com/r/discordapp/comments/rmt3yl/sync_with_computer_linux_behavior/

Not only it does not support other themes than Adwaita, but also it is only checked on startup, i.e. you must quit Discord and start it again in order for change to take effect. Ctrl+R does not help.

Is it possible to implement it the way other apps do it, i.e. from dconf?

Discord devs won't listen, you are my only hope.
