Initially to prevent issues with a few PHPUnit versions which were around in the early days of PHP 8.0, where these would accidentally be seen as parameter names. So, as a best practice, when using keys in data sets, the keys should match the parameter names of the receiving test method. An ulterior reason to make this change is that PHPUnit 11 will always treat the keys as parameter names, so this can be seen as a preparation step for allowing for PHPUnit 11 support in PHPCS 4.0.
