wrong authorization header upon publishing with creds

[skannengiesser]

I'm configuring helm-publish as follows:

helm {
    publishing {
        repositories {
            artifactory {
                url = uri('https://artifactory.example.com/my-helm-repo')
                credentials {
                    username = 'user'
                    password = 'pass'
                }
            }
        }
    }
}

Instead of the plugin writing the Basic Auth header as:

Authorization: Basic <base64-string> it writes
Authorization: Basic Basic <base64-string>

I think this is of prefixing the response of okhttp3 that also contains "Basic" literal with another "Basic" literal:

gradle-helm-plugin/src/main/kotlin/org/unbrokendome/gradle/plugins/helm/publishing/publishers/AbstractHttpHelmChartPublisher.kt

.addHeader("Authorization", "Basic ${Credentials.basic(username, password ?: "")}")
