Description of problem:

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. Follow https://github.com/openshift/console/blob/master/docs/helm/configure-namespaced-helm-repos.md for adding project helm chart repositories supporting basic auth.
2. If we create a repository and provide basicAuthConfig as shown in current documentation we will get an error.
3. The documentation here needs an update as the basicAuthConfig secret name should be specified with a `name` field

Actual results:

1. * spec.connectionConfig.basicAuthConfig: Invalid value: "string": spec.connectionConfig.basicAuthConfig in body must be of type object: "string"

   Expected results:

We should be able to add the repository supporting basic auth
