Configuration Documentation may be incorrect.

[tsacks]

The example documentation may be incorrect. It appears to have the 'redis' connection info inside of the 'queue' array, but it does not appear to work like that in practice.

I was only able to get that working by moving 'redis' from inside of 'queue' to inside of 'components' directly, and adding 'class' => 'yii\redis\Connection' to the 'redis' array.

Submitting a pull request with the changes in the documentation that has gotten it working for me.
