There is wrong 'test2-ds' deployment name in DeployedXmlDataSourceManagementTestCase.
It is causing wrong transformation if Batavia transformer is enabled because in case of
deployment name 'test2-ds' org.wildfly.galleon.plugin.transformer.JakartaTransformer.transform() method
doesn't recognize it's extension and so assumes it is a war deployment. This is causing
transformation errors when test is executed with transformer enabled. The proper solution
is to add '.xml' suffix to deployment so it is properly recognized by Galleon Batavia trasformer.
