List the Gradle plugin in the Maven repository runbookdocs/maven-gradle-plugin

maven.progmasoft.com/tazel serves the Gradle plugin of Tazel and its
plugin marker beside tazel-api, versions 0.2.0 through 0.4.0.3, but the
runbook named only the API. It now lists all three and shows how a
release stages the Gradle plugin: its build has no staging repository,
so an init script adds the same one the API uses.

+A release of Tazel publishes the API and the Gradle plugin into a local copy of the repository and copies it back, so
+that `maven-metadata.xml` keeps the versions published before. The build of the API has a `staging` repository; the
+build of the Gradle plugin has none, and an init script outside the checkout adds the same one:
+
+```kotlin
+// staging-plugin.init.gradle.kts
+allprojects {
+    if (name == "tazel-gradle-plugin") {
+        pluginManager.withPlugin("maven-publish") {
