docs: <p>
  Creates a new version of the bot based on the <code>$LATEST</code> version. If the <code>$LATEST</code> version
  of this resource hasn't changed since you created the last version, Amazon Lex doesn't create a new version. It
  returns the last created version.
  </p>
  <note>
  <p>
  You can update only the <code>$LATEST</code> version of the bot. You can't update the numbered versions that you
  create with the <code>CreateBotVersion</code> operation.
  </p>
  </note>
  <p>
  When you create the first version of a bot, Amazon Lex sets the version to 1. Subsequent versions increment by 1.
  For more information, see <a>versioning-intro</a>.

  This operation requires permission for the <code>lex:CreateBotVersion</code> action.
