Offline Build for JUnit 5 Project Fails - Missing `surefire-junit-platform:jar` dependency

### Affected version

3.5.4

### Bug description

# Description

I have a project that is set up to use JUnit 5 and the Maven Surefire plugin, per the [official documentation](https://maven.apache.org/surefire/maven-surefire-plugin/examples/junit-platform.html).
When trying to simulate a pre-fetched "offline build" workflow, builds that run tests fail because the Surefire plugin attempts to dynamically download the `surefire-junit-platform` JAR as a dependency.

# Expected Behavior

Surefire plugin declares all necessary dependencies for `go-offline` (and similar tools/plugins) to work, and/or the documentation provides necessary instructions for all dependencies to be declared up front.

# Actual Behavior

Build fails:

```sh
$ mvn clean package -o -Dmaven.repo.local=tmp-local
....
[INFO] --- surefire:3.5.4:test (default-test) @ single-module ---

```

# Reproducer

Using the "Hello World" example [here](https://github.com/adambkaplan/hermetoproject-integration-tests/tree/maven/single-module), run the following:

```sh
$ mvn org.apache.maven.plugins:maven-dependency-plugin:3.9.0:go-offline -Dmaven.repo.local=tmp-local
...
$ mvn clean package -o -Dmaven.repo.local=tmp-local
```

# Workaround

No clear workaround - adding the missing JAR as a plugin dependency leads to "classpath hell."

`pom.xml`:

```xml


org.junit.jupiter
junit-jupiter-engine
5.11.0
test

...

org.apache.maven.plugins
maven-surefire-plugin
3.5.4


org.apache.maven.surefire
surefire-junit-platform
3.5.4



```

Result:

```sh
[ERROR] There was an error in the forked process
[ERROR] org.junit.platform.commons.JUnitException: The wrapped NoClassDefFoundError is likely caused by the versions of JUnit jars on the classpath/module path not being properly aligned.
[ERROR] Please ensure consistent versions are used (see https://junit.org/junit5/docs/5.12.1/user-guide/#dependency-metadata).
[ERROR] The following conflicting versions were detected:
[ERROR] - org.junit.platform.commons: 1.11.0
[ERROR] - org.junit.platform.engine: 1.11.0
[ERROR] - org.junit.platform.launcher: 1.12.1
```

Start with the pom.xml and reproduce the issue using the documented go-offline command followed by mvn clean package -o with the temporary local repository. Trace how the Maven Surefire plugin resolves surefire-junit-platform:3.5.4 and compare that with the reported JUnit version conflict. Done means the reproducer completes an offline build without the workaround or classpath conflict.
