natvis not updated to 3.11.3

[RomanKhv]

Description

In version 3.11.3 the underlying namespace seems to be nlohmann::json_abi_v3_11_3.
But nlohmann_json.natvis is still written for nlohmann::json_abi_v3_11_2.

Reproduction steps

• Create sample project in Visual Studio.
• Add supplied nlohmann_json.natvis visuzliazer (https://github.com/nlohmann/json/blob/develop/nlohmann_json.natvis).
• Write some basic intialization for json object.
• Run in Debug mode and stop after initilization

Expected vs. actual results

In VS Debugger Watch window view for json object is not pretty-printed (visualizer is not applied)

Minimal code example

No response

Error messages

No response

Compiler and operating system

Library version

Validation

• The bug also occurs if the latest version from the develop branch is used.
• I can successfully compile and run the unit tests.

If you have Python installed, you can update it yourself using https://github.com/nlohmann/json/blob/master/tools/generate_natvis/generate_natvis.py

@nlohmann I guess executing this script should be added to the version update process.
