tour: Variables with initializers

[GermanMT]

Context: https://go-tour-lat.appspot.com/basics/9

The description of this basic says:
A var declaration can include initializers, one per variable. If an initializer is present, the type can be omitted; the variable will take the type of the initializer.

But in the code the integer declaration appears as: var i, j int = 1, 2
It's a small change, but maybe leave it as: var i, j = 1, 2 would make it clearer what is meant.
