Draft create should check for draft init

[razfriman]

I tried to create a draft for my project. after doing a fresh brew install of draft.
My first error was

Error: no languages were detected

So I forced the language to csharp. Then I see:

Error: No packs found with name csharp

Had to go into the docs to see that you need to first rundraft init to get the default plugins.

It would be nice for draft to do a check for this, or update the message to tell you that you forgot to init it
