Escape unicode character: u2028 #309

This is mostly a non issue and only has to do with JS/JSON interop. tl;dr: not all JSON is valid JavaScript. It'd be nice if we replaced the unicode line ending character with the equivalent \u2028 to make the output parseable as JavaScript.

Also \u2029: http://timelessrepo.com/json-isnt-a-javascript-subset

Technically, in ECMAScript 2019 (10th edition), it is no longer necessary, since the standard now allows U+2028 and U+2029 in strings. But it's probably better to err on the safe side (probably a lot of non-2019-compatible interpreters still out there) and just escape them. In Documenter we ran into this as well and we apply additional escapes on top of what JSON.json produces.
