Fix duplicate maven-source-plugin execution in docker-snapshot profile

[Copilot]

The docker-snapshot workflow failed with "We have duplicated artifacts attached" when running mvn install spring-boot:build-image. The spring-boot:build-image goal internally triggers the package phase, causing maven-source-plugin to execute twice—once during install and again during the re-executed package phase.

Changes

• Disabled maven-source-plugin execution in the docker-snapshot profile by setting phase to none
• Source JARs are unnecessary for Docker image builds and only needed for Maven artifact deployment

<profile>
    <id>docker-snapshot</id>
    <build>
        <plugins>
            <plugin>
                <artifactId>maven-source-plugin</artifactId>
                <executions>
                    <execution>
                        <id>attach-source</id>
                        <phase>none</phase>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

Regular builds and other profiles remain unaffected—source JARs are still generated for Maven deployments.

Original prompt

On maven.yml, when the docker-snapshot workflow is run we get this error:
