volkswargen typo

[nerdoc]

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. ;-)

That was surely helpful, to correct the typoz ;-) LOL

can't believe we need a PR for this, but okay, we do need things to work at least in this project LOL
