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).

Open the Compiler Options wiki page and compare its --target values with the tsconfig.json documentation, the JSON schema, and the referenced src/compiler/commandLineParser.ts entry. Update the documentation so the capitalization matches the schema and code, then check that the linked documentation no longer gives conflicting guidance.
