Fix colorization of "hash" in SAIO doc.
Fix colorization of "hash" in SAIO doc.

Admittedly, this is ridiculously trivial, but the coloring of
"hash" always peeved me. Not so much that it existed, but that
I did not understand what caused it. After consulting our Sphinx
experts, it turned out that the code block was considered code
in Python and "hash" is a reserved word in Python, so it was
colored.

One option is to declare the code block "ini", which is what
it is, but that causes the block stand out just as badly, unless
we highlight every one of them. So, for now use "none".
