'message' attribute is optional in junit.xsd

The xunit report produced by cargo-nextest can't be imported by sonar-rust due to invalid assumption that message attribute is mandatory:

20:28:11.239 DEBUG: Using pattern './target/nextest/gitlab/cargo-nextest-run.junit.xml' to find reports
20:28:11.254 WARN: Cannot read report './target/nextest/gitlab/cargo-nextest-run.junit.xml', the following exception occurred: Missing attribute 'message' at line 11
