storage.sgml mentioning htup.h when referring to HeapTupleHeaderData

Hi all,

I found the following mistake in the docs while looking at another patch:
diff --git a/doc/src/sgml/storage.sgml b/doc/src/sgml/storage.sgml
index 0153b08..164d08c 100644

    All the details can be found in
-   <filename>src/include/access/htup.h</filename>.
+   <filename>src/include/access/htup_details.h</filename>.

Patch is attached.
