title: How to rename a cocoapod
body: <p>I have a published Cocoapod, say it's named <code>abc-sdk</code>, I wish to fix its name (capitalization) to <code>Abc-SDK</code>. Is it possible?
  I tried changing the <code>s.name</code> in the podspec (and the podspec file name capitalization as well) but when I run <code>pod trunk push</code> I get:
  <code>
  [!] The following validation failed:
  - Name is already taken.
  </code>
  What's the right way to do it?</p>
