Better way to pass arguments to Logger tap

[smitoi]

Hello,

I needed a small feature - logging with a token prefixed to my message (depending on the specified logger) - I found that the best way would be to define a 'tap' option, and I wanted it with a generic class that would modify the format of the message with a passed argument, but I observed that (a) it's not documented anywhere how you should pass arguments and (b) it's pretty ugly to give arguments since they can only be passed as a string, not as an array, and this comes with some limitations. The idea would be to allow to specify tap like this:

[
    'tap' => [
        [App\Log\Prefixer::class, 'Argument 1', 2, env('ARG_3')],
    ],
]

I already made my way through the code to make this small change and I could make a pull request, but is this worth pursuing / the right way to contribute?

Thank you!
