Disable filepath formatting as a link for Drone CI's output

It seems, default console output was changed some time ago. It had been clear and easy-to-read, but then it turned into something like this:

ERROR: MissingReturnType - �]8;;file:///path/to/File.php#L9�\src\File.php:9:30�]8;;�\ - Method App\File::canBuild does not have a return type (see https://psalm.dev/050)
        abstract public function canBuild();

Using --long-progress CLI option doesn't help, unfortunately.
