Change plugins.svn linting to PHP 7.current please

As a follow up to https://make.wordpress.org/systems/2018/03/12/change-all-svn-php-linting-to-php7/ and https://meta.trac.wordpress.org/ticket/3791 can we please switch the PHP linting for plugins.svn to 7.2 and keep it up-to-date with newer PHP branches as they’re deployed for WordPress.org?
