moodle minor upgrade

An update for doing minor point upgrades to moodle - much simpler than what I have listed at 
https://hnsws.blogspot.com/2021/08/detailed-steps-for-moodle-upgrade-using.html

Just

cd /var/www/theLMSgit

sudo -u www-data /usr/bin/php admin/cli/maintenance.php --enable

git pull

sudo chown -R azureuser:www-data .

sudo chmod -R 775 .

sudo -u www-data /usr/bin/php admin/cli/upgrade.php

(type y when prompted)

sudo -u www-data /usr/bin/php admin/cli/maintenance.php --disable

cd our-notifier-folder

sudo ./startupscript.sh

(can check out.log to see if server has started)

We can then test notifications using Site Administration - Messaging - Mobile - Check and test push notification configuration - that page asks us to make sure that "your devices are connected to the Internet and that the mobile app is not open (since push notifications are only displayed when received in the background)."
