Subject: [PATCH] Allow Symfony 8 and fix PHP 8.4+ nullable deprecations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

symfony/finder was capped at ^7, which blocks installing the library in
any Symfony 8 project. Widen it to ^8 (and var-dumper/phpunit for dev).

Also declare the two implicitly-nullable parameters explicitly —
PHP 8.4 deprecates `Type $x = null`:

- CnbRates::getRates()
- NameDaysAbstract::getNameDay()

Tested on PHP 8.5.6 with symfony/finder 8.1.1: CnbRatesTest and
NameDayTest pass. OpenWeatherTest still needs a WEATHER_API key and
fails without one, unchanged by this PR.
