volkswargen typo

in the README.md, you point to
```
[! [volkswagen status](https://auchenberg.github.io/volkswagen/volkswargen_ci.svg?v=1)](https:
//github.com/auchenberg/volkswagen)
```
but it says "volkswargen_ci" instead of "volkswagen_ci". Unfortunately, the badge itself is named wrong too, so you have to correct both.
