Mark passwords and URIs as #[\SensitiveParameter] (PHP 8.2+)

[SimonFrings]

As @clue describes in friends-of-reactphp/mysql#162:

This changeset marks all passwords and URIs containing passwords as #[\SensitiveParameter] to avoid these parameter from potentially showing up in exception traces in PHP 8.2+. Older PHP versions are not affected by this change and continue to work as is. See also RFC: https://wiki.php.net/rfc/redact_parameters_in_back_traces
