Although PHP 8.1 is the stock version in Ubuntu 22.04, it's not supported by Nextcloud yet, and it likely will never be supported by the the version of Nextcloud that succeeds the last version of Nextcloud that supports PHP 7.2, and we have to install the next version so that an upgrade is permitted, so skipping to PHP 8.1 may not be easily possible.
* Fix path to bind9 startup options file in Ubuntu 22.04.
* tinymce has not been a Roundcube requirement recently and is no longer a package in Ubuntu 22.04
* Upgrade Vagrant box to Ubuntu 22.04

(Updated by @JoshData from the original commit which was for Ubuntu 20.04 using PHP 7.4. And although 8.1 seems to be available, it's not supported by Nextcloud yet, and it likely will never be supported by the the version of Nextcloud that succeeds the last version of Nextcloud that supports PHP 7.2, and we have to install the next version so that an upgrade is permitted, so skipping to PHP 8.1 may not be easily possible.)
* Update php-xsl to php8.0-xml for zpush.

* Upgrade Vagrant box to Ubuntu 22.04
