render_esi is not configured by default

`render_esi` does not work with the default configuration.

Steps to reproduce:
1. In a template, use the following:

{{ render_esi(controller('ez_content:viewAction', {locationId: 2, viewType: 'full'} )) }}

2. Preview the content.
You will see an error: "An exception has been thrown during the rendering of a template ("The "esi" renderer does not exist.")."

Note: config/packages/framework.yaml by default has #esi: true commented out
