Going to a package from search on hexdocs

[cheerfulstoic]

On the new hexdocs, I miss the functionality to be able to just enter a package and then just go straight to the docs. I generally don't want to be searching across many packages 🤷 (though I really like that you can search across many packages for projects like Phoenix, that's amazing 👍)

We would welcome a PR that adds a button called "Go to docs", close to Search, that opens up a model and allows you to choose a package (the same pressing g in ExDoc works).
