Add argument for php-unit pre-commit vendor path?

[jasonglisson]

I have a unique setup using docker and my composer file as well as vendor directory are nested on directory inside of the project. The Pre-commit checkout keeps saying:

Please have one available as one of the following:

• phpunit.phar
• vendor/bin/phpunit
• phpunit

PHPUnit is found at docroot/vendor/bin/phpunit in my project but I can't figure out how to get this recognized.
