[docs] BUG: Bad footnote in library/profile.html

At http://docs.python.org/library/profile.html#id1, the footnote [1] links to a note about the documentation. Based on the context, it should be linked to the second footnote, which is "Prior to Python 2.2, it was necessary to edit the profiler source code to embed the bias as a literal number. You still can, but that method is no longer described, because no longer needed."
