Migrate content to docs/quick-docs

[sanjayankur31]

Hi there,

Given that docs is now up and running, should the dev portal just be merged into them?

https://docs.fedoraproject.org/en-US/docs/

That way there's one place for users to find documentation, and all of docs can be translated etc too. A lot of the material on here seems like it'd fit right in with quick-docs for example:
