README config example typo: "autowiring" should be "autowire"

[gmpf]

There's a typo in the "Using autowiring…" section of the README. It says

autowiring: true

as opposed to

autowire: true

I copy-pasted the example and Symfony yelled at me in its signature style. ;)

In FileLoader.php line 166:
The configuration key "autowiring" cannot be used to define a default value in "[…]/config/services.yml". Allowed keys are "public", "tags", "autowire", "autoconfigure", "bind" in "[…]/config/services.yml" (which is being imported from "[…]/config/config.yml").

Thanks for pointing this out!
