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).

Apri la pagina wiki Compiler Options e confronta i relativi valori di --target con la documentazione di tsconfig.json, lo schema JSON e la voce referenziata di src/compiler/commandLineParser.ts. Aggiorna la documentazione in modo che le maiuscole e minuscole corrispondano allo schema e al codice, quindi verifica che la documentazione collegata non fornisca più indicazioni contrastanti.
