fix: CronJob Property 'comment' do not exist replace by note_private

[FHenry]

Should we change module template boilerplate and all core module cronjobs creation on activation to change array key name from "comment" to "note_private" to keep consistancy between declaration and field name ?
like in

dolibarr/htdocs/core/modules/modAgenda.class.php

Line 125 in b2bad15

0 => array('label' => 'SendEmailsReminders', 'jobtype' => 'method', 'class' => 'comm/action/class/actioncomm.class.php', 'objectname' => 'ActionComm', 'method' => 'sendEmailsReminder', 'parameters' => '', 'comment' => 'SendEMailsReminder', 'frequency' => 5, 'unitfrequency' => 60, 'priority' => 10, 'status' => 1, 'test' => 'isModEnabled("agenda")', 'datestart' => $datestart),

or

dolibarr/htdocs/modulebuilder/template/core/modules/modMyModule.class.php

Line 276 in b2bad15

// 'comment' => 'Comment',
