x/website: somebody please change getting started

[mvijay73]

Please change the sample code in the actual getting started page. It still has the broken code. The new part to add the greetings.go is not there and that is confusing.

[ALTree]

Please clarify what error are you reporting, and provide a link the offending website page, it's not clear what the problem is.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
