Andreas Jaeger 8ed66d957b propose_update.sh: Don't output complete git diff
When this script is invoked from the propose-openstack-manuals-updates
job, it can easily generate several 10k lines of diff.

The git diff command outputs all of them.

Use "git diff --stat" instead for a very brief output.
