Log channel is ignored

[Radiergummi]

If the environment variable ELASTIC_LOGGER is set, and/or the configuration directive es.logger points to a log channel as configured in config/logging.php, it is ignored and an instance of the default logger is passed to the Elasticsearch client factory instead.
This is caused by the provider properly checking for the logger, but injecting the PSR LoggerInterface instead of the configured logger instance:

$logger = Config::get('es.logger') && $app->bound('es.logger')
    ? $app->make(LoggerInterface::class)
    : null;

Instead, we should inject the logger by its identifier:

$logger = Config::get('es.logger') && $app->bound('es.logger')
    ? $app->make('es.logger')
    : null;
