Updated locations of stable and incubator Helm repositories (#125)

* Updated locations of stable and incubator Helm repositories

otherwise `Add dependency chart repos` step fails with following
message:

```
Error: repo "https://kubernetes-charts.storage.googleapis.com/" is no
longer available; try "https://charts.helm.sh/stable" instead
```

with a similar message for `incubator` repository

* Removed `Add dependency chart repos`

Jenkins chart doesn't defined any dependencies anyway
