Replaced xstreams with javax.xml for Gradle 8.4 compatibility (#814)

If you still have a legacy xml provider listed in your buildEnvironment dependency tree, such as old version of xerces, then you can force the default provider to OpenJDK's by adding the following to your gradle.properties.

systemProp.javax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
systemProp.javax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
systemProp.javax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
