Failure on teardown is not considered as test error/failure

### Jenkins and plugins versions report

Jenkins: 2.346.3
OS: Windows Server 2019 - 10.0
Java: 1.8.0_402 - Amazon.com Inc. (OpenJDK 64-Bit Server VM)

xunit:3.1.0

### What Operating System are you using (both controller, and any agents involved in the problem)?

Windows Server 2019 - 10.0

### Reproduction steps

* On one of test-suite, error on teardown occurred (test executed successfully and passed):
executed="True" result="Failure" success="False"

* On general status of test-results:
errors="0" failures="0"

### Expected Results

* On one of test-suite, error on teardown occurred (test executed successfully and passed):
executed="True" result="Failure" success="False"

* On general status of test-results:
errors="1" failures="1"

### Actual Results

* On one of test-suite, error on teardown occurred (test executed successfully and passed):
executed="True" result="Failure" success="False"

* On general status of test-results:
errors="0" failures="0"

### Anything else?

Would be nice to have an option on the plugin to treat errors on any part of the test as a failure

### Are you interested in contributing a fix?

_No response_

Start by reproducing the teardown-error scenario with the reported Jenkins, NUnit, and xUnit versions on Windows. Trace how the plugin aggregates suite results when a test has result="Failure" and success="False"; done means the overall result reports errors="1" and failures="1", with the requested behavior covered by a regression test.
