Maven: UpgradePluginVersion does not work for plugins in pluginManagement

What version of OpenRewrite are you using?

I am using org.openrewrite.maven:rewrite-maven-plugin:5.28.0

How are you running OpenRewrite?

I am using the Maven plugin, and my project is a single module project. I am using the following pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project
	xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/maven-
v4_0_0.xsd">

	<artifactId>demo</artifactId>
	<version>0.1.0-SNAPSHOT</version>
	<packaging>pom</packaging>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<info.version>3.4.5</info.version>
	</properties>
	<build>
		<pluginManagement>
			<plugins>
				<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-project-info-reports-plugin</artifactId>
					<version>${info.version}</version>
				</plugin>
				<plugin>
					<groupId>org.sonarsource.scanner.maven</groupId>
					<artifactId>sonar-maven-plugin</artifactId>
					<version>3.10.0.2594</version>
				</plugin>
			</plugins>
		</pluginManagement>
		<plugins>
			<!-- put the plugin here and the update will be performed...
<plugin><groupId>org.sonarsource.scanner.maven</groupId><artifactId>sonar-maven-plugin</artifactId><version>3.10.0.2594</version></plugin>
-->
		</plugins>
	</build>
</project>

As a sibling to pom.xml the following rewrite.yml exists:

---
type: specs.openrewrite.org/v1beta/recipe
name: demo
displayName: Upgrade Maven plugin versions
recipeList:
  - org.openrewrite.maven.UpgradePluginVersion:
      groupId: org.apache.maven.plugins
      artifactId: maven-project-info-reports-plugin
      newVersion: latest.release
  - org.openrewrite.maven.UpgradePluginVersion:
      groupId: org.sonarsource.scanner.maven
      artifactId: sonar-maven-plugin
      newVersion: latest.release

What is the smallest, simplest way to reproduce the problem?

See the setup above; I am running mvn org.openrewrite.maven:rewrite-maven-plugin:5.28.0:run -Drewrite.activeRecipes=demo

What did you expect to see?

I expected the recipe to update both the property and the version of the plugins declared in <pluginManagement/>.

What did you see instead?

No modification occurred, the plugins are not updated.

Note when I declare a plugin in <plugins/> instead, an update is performed. I am using <pluginManagement/> because my ultimate use would be also in multi-module projects.

What is the full stack trace of any errors you encountered?

No errors, no stracktrace, just no expected updated plugin versions.

Are you interested in contributing a fix to OpenRewrite?

Sorry, I can't.

Reproduce the issue with the provided pom.xml and rewrite.yml by running the documented Maven rewrite-maven-plugin command. Start from org.openrewrite.maven.UpgradePluginVersion and compare handling of build/pluginManagement with build/plugins. Done means both pluginManagement entries are updated, including the referenced property where applicable.
