tutorial:  land height is "elevation", not "altitude"

This is a follow-on patch to 92c12e46d5.  In that patch, we renamed
"altitude" to "elevation" in the docs, based on these details:

   https://mapscaping.com/blogs/geo-candy/what-is-the-difference-between-elevation-relief-and-altitude

This renames the tutorial SQL files to match the documentation.
