Inspired while #61371 , but can be merged separately.

``@PHPxMigration`` and ``@Symfony`` ruleset have different config for those rules. I assume the difference is coming from supporting pre-7.2 PHP version earlier in the codebase, where heredoc closure and trailing comma had to be on separated lines - but it's no longer the case.

Can we benefit from newer PHP syntax and incorporate those changes? (yes, `trailing_comma_in_multiline`, part of ``@Symfony``, is already having this enabled!)
if so, i will also merge them into ``@Symfony`` ruleset itself afterwards.
