Description

It would be useful to add an output context to HTL to be used inside JSON. As JSON is very complex, the most essential one which currently cannot be achieved with any other existing contexts is escaping for a JSON String value (compare with https://github.com/adobe/htl-spec/issues/5).
I propose to introduce a new context jsonString next to scriptString in https://github.com/apache/sling-org-apache-sling-scripting-sightly/blob/192d953514e6e579428cda157a7e83fc2a05cc01/src/main/java/org/apache/sling/scripting/sightly/impl/engine/extension/XSSRuntimeExtension.java#L93.

As it is not part of the official HTL spec at https://github.com/adobe/htl-spec/blob/master/SPECIFICATION.md#121-display-context it needs to be listed as Sling-specific addition in https://sling.apache.org/documentation/bundles/scripting/scripting-htl.html#extensions-of-the-htl-specification.
