Update Moodle version

update-moodle.sh

# Script: update-moodle.sh
# From: https://gist.github.com/
# This script will update Moodle within the same major version (example: 3.6.1 to 3.6.3).
# The nice thing about this simple approach is that it won't affect your plugins.
# Assumes you used "git clone" to create and install your instance of Moodle. If you did not, don't use this script!
