[Idea] Start to use github discussions

[zabidenhtf]

Yes, this issue not about Li-Ri, this is about github. Because ideas need to be in discussions, not in issues. And also if you add discussions page you can remove my ideas from issues tracker.

I've added the discussions, let's see how it goes. I can convert all the [Idea] issues to discussions, is it fine with you?

[zabidenhtf]

Yes, sure you can transfer my ideas into discussions
