Ports the ZipStreamWriter class from WordPress Blueprints PHP library to replace the zipstream-php library that only works with PHP 8.2. It probably works with PHP 7.2, too, but I haven't tested it there yet. cc @bgrgicak
Testing instructions
Attempt cloning the site in wp-admin (Tools > Sandbox site), confirm that it worked.
