Add new scriptlet — 'trusted-json-set'

[contribucious]

Hello,

Basically, in the continuity of the json-prune scriptlet (and the $jsonprune modifier, allowing more advanced queries currently), it can be pretty neat and logical to have a trusted-json-set scriptlet (and a $jsonset modifier), I would say. To either define new or modify existing JSON properties, instead of pruning them.

Some websites / web apps (TF1, M6 too nowadays, etc.) require certain (ad-related) JSON properties to be both present and boolean.
↪️ Currently fixed using JS rules but hey … let's improve/simplify that! 😉

Thank you very much! 👍

P.S. In a discussion I had a while ago with @ameshkov, there was talk of a possible untrusted version limited to true/false/etc. (i.e. a basic json-set scriptlet, thus following the same pattern as set-constant and trusted-set-constant), but probably still too risky though, I would say.
