Documentation for extensions.json format missing

[ramya-rao-a]

Run the command Extensions: Configure Workspace Recommended Extensions
It opens a file with below content

{
    // See http://go.microsoft.com/fwlink/?LinkId=827846
    // for the documentation about the extensions.json format
    "recommendations": [
        // Extension identifier format: ${publisher}.${name}. Example: vscode.csharp

    ]
}

http://go.microsoft.com/fwlink/?LinkId=827846 takes you to the extensions page that doesnt have any docs for the extensions.json format

Need to update fwlink 827846 once the 1.6 release is published.
