dokka-maven-plugin ignores non-standard maven local repo

[adangel]

Describe the bug
When you run your maven build and use a local maven repo at a non-standard location (not ~/.m2/repository), then dokka-maven-plugin still downloads dependencies there. If you want to keep your dependencies separate, that's not possible then.

Expected behaviour
When Maven is configured or instructed to use a specific location for the local maven repository, then the default local repo location should not be modified.

To Reproduce

• A maven project with the dokka-maven-plugin added
• clear your default local maven repo location (e.g. mv ~/.m2/repository ~/.m2/repository-old)
• run mvn clean verify -Dmaven.repo.local=$(pwd)/m2repo

Now all dependencies should be placed into ./m2repo and ~/.m2/repository should not exist.

Dokka configuration

            <plugin>
                <groupId>org.jetbrains.dokka</groupId>
                <artifactId>dokka-maven-plugin</artifactId>
                <version>${dokka.version}</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>javadocJar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Installation

• Operating system: Linux
• Build tool: Maven
• Dokka version: 1.4.10.2

Additional context
The path ~/.m2/repository seems to be hard coded here:

dokka/runners/maven-plugin/src/main/kotlin/DokkaMojo.kt

Line 268 in eba2508

val localRepo = LocalRepository(System.getProperty("user.home") + "/.m2/repository")

Hi, since you already debugged what is the cause of this behaviour would you mind contributing a PR for that?
