Update gsg-php-composer.html.md.erb

Changed the COMPOSER_INSTALL_OPTIONS defaults to show this is a "list" (a JSON array)

This fixes part of https://github.com/cloudfoundry/php-buildpack/issues/309 where one of the reported issues is that, if you make this a string, then the composer install command would become: composer install - - n o - i n t e r a c t i o n - - n o - d e v - - n o - p r o g r e s s. This is what happened to me too and I have been searching for quite a while for what could be the problem and what could be the solution. If the default in the docs shows a list, then it will be much clearer to its readers that they should add this to the options.json as a list.
