Add Ember to the Frameworks section

[mansona]

Hey there 👋

First of all, what a great site 🎉 It's always great to see people putting so much effort into making sure people know what resources there are out there to learn (especially the more complicated the web dev world gets!)

I noticed that Ember is missing from the framework section. I'll see if I can put together a quick PR to add it if that helps, I found the data folder and I think I know what is needed to add it 😂
