Bug & fix patch: contrib-guide

[Yotam Medini]

Hello,

Attached is a patch, fixing a build problem.
When making
   Documentation/devel contrib-guide.txt
The following error appears:

LANG= makeinfo --enable-encoding -I
/home/yotam/src/lilypond/dev/lilypond/Documentation/user -I. -I./out
--no-split --no-headers --output out/contrib-guide.txt
out/contrib-guide.texi
./lsr-work.itexi:202: `Updating LSR to a new version' has no Up field
  (perhaps incorrect sectioning?).

./lsr-work.itexi:154: Next field of node `Fixing snippets in LilyPond
  sources' no t pointed to (perhaps incorrect sectioning?).
./lsr-work.itexi:202: This node (Updating LSR to a new version) has the bad 
Prev.
makeinfo: Removing output file `out/contrib-guide.txt' 
  due to errors; use --force to preserve.
make[2]: *** [out/contrib-guide.txt] Error 1

The patch changes some @subsection to @section 
and fixes a typo s/Uptating/Updating/.
