Add support for the #[WithMonologChannel] attribute of Monolog 3.5 to autoconfigure the channel

[stof]

Configuring custom channels on some services is one of the last reasons I have for defining services explicitly in my config files. This attribute allows to solve that.

use Monolog\Attribute\WithMonologChannel;
use Psr\Log\LoggerInterface;

#[WithMonologChannel('fixture')]
class ServiceWithChannel
{
    public function __construct(private LoggerInterface $logger) {}
}

Suggested change

	public string $channel;
	public $channel;

[stof]

IMO, it is fine to keep the typed property there. Attributes don't work on PHP 7.2 anyway

[nicolas-grekas]

why not using CPP then?

[stof]

ah indeed. For some reasons, I thought CPP was 8.1 like the readonly properties.

[lyrixx]

👍🏼 I like it

[derrabus]

Can we please write tests for that? And should we move the attribute to the bridge?

[nicolas-grekas]

should we move the attribute to the bridge?

Or better: to monolog itself?

We already have https://github.com/Seldaek/monolog/blob/main/src/Monolog/Attribute/AsMonologProcessor.php

[stof]

@Seldaek do you think this attribute should go in Monolog itself ?

[stof]

I submitted it to Monolog in Seldaek/monolog#1847
If this is accepted, I will update this PR to use the Monolog attribute instead.
