docs: def list_server_certificates(path_prefix='/', region=None, key=None, keyid=None, profile=None):
      '''
      Lists the server certificates stored in IAM that have the specified path prefix.
  
      .. versionadded:: ???
  
      :param path_prefix:
          The path prefix for filtering the results.  For example:  /company/servercerts would get
          all server certificates for which the path starts with /company/servercerts .
          This parameter is optional.  If it is not included, it defaults to a slash (/), listing all
          server certificates.  This parameter allows (per its regex pattern) a string of characters
          consisting of either a forward slash (/) by itself or a string that must begin and end with
          forward slashes.  In addition, it can contain any ASCII character from the ! (u0021)
          through the DEL character (u007F), including most punctuation characters, digits, and upper
          and lowercased letters.
  
      CLI Example:
  
      .. code-block:: bash
