fix: fix duplicate jaxb-core dependency

[mlopezFC]

Close #187

This PR resolves the duplicate jaxb-core-4.0.6.jar dependency issue that prevented users from upgrading to version 2.5.x when building WAR files with Gradle. The problem occurred because both docx4j-JAXB-ReferenceImpl and docx4j-JAXB-MOXy transitively included different implementations of the same JAXB core library under different Maven group IDs (org.glassfish.jaxb:jaxb-core and com.sun.xml.bind:jaxb-core).

The fix adds a Maven exclusion to the docx4j-JAXB-MOXy dependency, excluding com.sun.xml.bind:jaxb-core while keeping the GlassFish reference implementation. This change has been verified with a clean dependency tree, successful build, all unit tests passing and also manual testing of the demo.
