Important: #79847 - Fluid bugs fixed and features added (Fluid 2.3.1)

See Issue #79847

Description

The Fluid engine dependency is raised to version 2.3.1 which fixes a few important bugs and adds a couple of features:

This means two things:

  1. For template developers this means you can use {escaping off} in a template to completely disable the escaping which is normally done - which can be particularly helpful in non-HTML templates.
