v2 migration docs missing some elements

[3flex]

Describe the bug
I tried following the migration guide for v2 but got stuck at a few points migrating the following:

    tasks.withType<DokkaTask>().configureEach {
        suppressInheritedMembers = true
        failOnWarning = true
        outputDirectory = layout.projectDirectory.dir("../website/static/kdoc/detekt-gradle-plugin")

        dokkaSourceSets.configureEach {
            apiVersion = "1.4"
            externalDocumentationLink {
                url = URI("https://docs.gradle.org/current/javadoc/").toURL()
            }
        }
    }

The migration guide suggests tasks.withType<DokkaTask>().configureEach { is replaced with dokka { but some parameters aren't supported on the new extensions.

There is no guidance in deprecation warnings in the IDE, nor documentation in the migration guide, for these task properties:

• failOnWarning
• externalDocumentationLink

Expected behaviour
Migration guide should cover all changes to existing properties, whether they're now unsupported, or have a replacement.

To Reproduce
Set this in a project with dokka plugin applied:

dokka {
    failOnWarning = true
    outputDirectory = layout.projectDirectory.dir("../website/static/kdoc/detekt-gradle-plugin")

    dokkaSourceSets.configureEach {
        apiVersion = "1.4"
        externalDocumentationLink {
            url = URI("https://docs.gradle.org/current/javadoc/").toURL()
        }
    }

    dokkaPublications.configureEach {
        suppressInheritedMembers = true
    }
}
