Xdebug-tunnel open fails with 'php_xdebug_package' is undefined

Hi, any pointers why xdebug-tunnel might fail with this setup? We are on the current trellis version, but still using PHP 7.4. Everything should be configured, but the php7.4 settings in /trellis/roles/php/vars seemingly don’t get used.

Cheers
Philipp
