Upgrade phpdocumentor (#2649)

* phpDocumentor 3.5.3 → 3.7.1

Fix `PHP Parse error:  syntax error, unexpected token ":" in phar:///private/tmp/ibexa-dxp-phpdoc/phpDocumentor.phar/vendor/twig/twig/src/Environment.php(418) : eval()'d code on line 58`

* Use phpDocumentor 3.7.1 templates

Only change template.js and template.css (seems to add some SVG diagram support)

(cherry picked from commit 5af3fd6)
