title: StyleCop.Analyzers: Disable SA1633 & SA1652
body: <p>I have already consulted the <a href="https://github.com/DotNetAnalyzers/StyleCopAnalyzers/blob/master/documentation/Configuration.md" rel="noreferrer">configuration documentation</a>, but couldn't find anything.</p>
  
  <p>I want to disable both of the following rules:</p>
  
  <pre><code>SA1633: The file header is missing or not located at the top of the file.
  SA1652: Enable XML documentation output.
  </code></pre>
  
  <p>My <code>stylecop.json</code> looks like this:</p>
  
  <pre><code>{
    "$schema": "https://raw.githubusercontent.com/DotNetAnalyzers/StyleCopAnalyzers/master/StyleCop.Analyzers/StyleCop.Analyzers/Settings/stylecop.schema.json",
    "settings": {
      "orderingRules": {
        "usingDirectivesPlacement": "outsideNamespace"
      }
    }
  }
  </code></pre>
  
  <p>Any ideas?</p>
