/// Synchronously renames this link. Returns a Link instance for the renamed
/// link.
///
/// If newPath identifies an existing link, that link is replaced. If newPath
/// identifies an existing file or directory the operation fails and an

/// @description Checks that this method synchronously renames this link and

/// @note The test should run with the Administrator priveleges on Windows.
/// Dart API Spec reads:
/// In order to create a symbolic link on Windows, Dart must be run in
/// Administrator mode or the system must have Developer Mode enabled, otherwise
/// a FileSystemException will be raised with ERROR_PRIVILEGE_NOT_HELD set as
/// the errno when this call is made.
