[Logger] Use Monolog\LogRecord object instead of array for log processor

Leverage new monolog as log records object (monolog >= v3) https://github.com/Seldaek/monolog/releases/tag/3.0.0

if we decide to keep the array (monolog <= v2), how can we document this? with inline comments ? with 2 code block?

see also https://packagist.org/packages/monolog/monolog/php-stats#3.0 that is why I target sf 6.1+

thx
