Fixes #2678
json需要放到工具栏中

Summary

Added JSON to the "Inline code" and "Block of code" menus in toolbar.

Developer Document: devel/209_18.md

Issue Found

Users were unable to insert JSON code blocks directly from the editor's code menu because the option didn't exist.

Changes

In TeXmacs/progs/prog/prog-menu.scm:

• Added ("JSON" (make* 'json "json")) to the "Inline code" submenu.
• Added ("JSON" (make* 'json-code "json")) to the "Block of code" submenu.

In TeXmacs/plugins/json/progs/code/json-lang.scm:

• Updated the numeric literal parser-feature to check for lan "json" instead of "javascript".
• Updated the texmacs-module definition to include (:use (prog default-lang)).

- (texmacs-module (code json-lang))
+ (texmacs-module (code json-lang)
+   (:use (prog default-lang)))

How to Test

1. Open Mogan.
2. Go to the code menu in the toolbar or Insert -> Code.
3. Verify that JSON appears under both Inline code and Block of code.
4. Select JSON under Block of code and verify it inserts a <json-code|...> block.
