Composer instructions do not work

[davejagoda]

Describe the bug

The instructions to use composer to install pure-css don't work.

To Reproduce

$ composer --version
Composer version 2.7.1 2024-02-09 15:26:28
$ composer require pure-css/pure

Installation failed, deleting ./composer.json.

In RequireCommand.php line 226:
                                                                                                                          
  No composer.json present in the current directory (./composer.json), this may be the cause of the following exception.

Possibly related, the Yahoo GitHub URL redirects to the pure-css one:

$ curl -s -L -I https://github.com/yahoo/pure | grep location
location: https://github.com/pure-css/pure

The Packagist page for purecss: https://packagist.org/packages/yahoo/purecss points to the Yahoo GitHub URL. Perhaps there's a way to update the Packagist page and make the non-Yahoo URL work.
