Trollestia probably planted it there for Twilight to find. Come on, since when does Celestia give her "Most Faithful Student" a straight answer when she could lay a trail of breadcrums for her to follow and find the answer herself? Even with something this big it's possible that she's playing the same mind-games with Twilight. On the flip side, it's possible that the keys have to be found this way - by effort on the part of the ones who will turn them.

The fact that the journal probably also contains embarrassing little details about Luna's adolescence that Celestia would find amusing to have known by a wider audience (such as Luna's good, close friend and astronomy collaborator, Twilight Sparkle) is probably part of it too.
