Documentation/git-config.txt: AsciiDoc tweak to avoid leading dot

Bram Schoenmakers noticed that git-config document was formatted
incorrectly.  Depending on the version of AsciiDoc and docbook
toolchain, it is sometimes taken as a numbered example by AsciiDoc,
some other times passed intact to roff format to confuse "man".

Since we refer to the repository metadata directory as $GIT_DIR
elsewhere, work it around by using that symbolic name.

 If not set explicitly with '--file', there are three files where
 git-config will search for configuration options:
 
-.git/config::
+$GIT_DIR/config::

        of course relative to the repository root, not the working
        directory.)
