As fromTOML supports \u and \U escapes, bring fromJSON on par. As JSON defaults to UTF-8 encoding (every JSON parser must support UTF-8), this change parses the `\u hex hex hex hex` sequence (\u followed by 4 hexadecimal digits) into an UTF-8 representation. Add a test to verify correct parsing, using all escape sequences from json.org.

As far as I can tell, this code has not been released yet. When will it be included in a release? Will/can it be back-ported to 2.3? |

Support for Unicode escape sequences (`\uabcd`) was added to Nix in version 2.4 (NixOS/nix#3305), so in order to maintain compatibility with 2.3 (which IMO is debatable) we should output non-ASCII characters as-is.

Caught by @basvandijk while debugging Hydra issue, where JSON strings coming from GitHub contained
\ u(on purpose written with a space in between to avoid this Hydra issue), which prevented the evaluation of any jobset in a project, as JSON parsing was failing.Fixes #2257
