This updates PHPMailer to the latest version. Please see the changelog on their repo (https://github.com/PHPMailer/PHPMailer/releases) if you are interested. To test this ensure that sending emails in Joomla works as expected
libraries/vendor/phpmailer/phpmailer/extras/README.md and libraries/vendor/phpmailer/phpmailer/get_oauth_token.php should be added to gitignore and removed from this PR
libraries/vendor/phpmailer/phpmailer/extras/class.html2text.php needs to be added to the list of deleted files in the update script
I have tested this item successfully on 0ac03aa
