I think it has to do with wave lengths and frequencies.
The pressure of the stram must make something vibrate, and since the length of the spout is just right, waves of pressure are put into the steam. These waves hit us with the same frequency as the thing that the steam makes vibrate so we hear that tone.
it's the same way all wind instroments work

Its just like a flute. The cap is made with a whistle in it. Various hole sizes and the air (steam) creates a cavitating vibration. Resonations.

For the same reason that you make noise when you force air through puckered lips: the friction of the air.
