Compiler "target" option capitalization in docs inconsistent with code and json schema

https://github.com/Microsoft/TypeScript/wiki/Compiler-Options
says --target can take the value ES5 (uppercase).

Visual Studio Code warns about using the uppercase one in your tsconfig.json, presumably because it's following the schema.

The JSON schema for tsconfig.json also has it in lowercase, but the docs (https://github.com/Microsoft/TypeScript/wiki/tsconfig.json#details) refer you to the first page (which uses uppercase) for the values.

My guess at fixing the problem:

From the source it appears the value ought to be lowercase:
https://github.com/Microsoft/TypeScript/blob/master/src/compiler/commandLineParser.ts#L221

I think the fix is to use lowercase in the docs (the first page).

打开 Compiler Options wiki 页面，并将其中的 --target 值与 tsconfig.json 文档、JSON schema 以及所引用的 src/compiler/commandLineParser.ts 条目进行比较。更新文档，使大小写与 schema 和代码一致，然后检查链接的文档不再提供相互冲突的指导。
