[SUREFIRE-2269] Error during clean project after build GitHub - Mac OS

After switch to executing ITs in parallel - SUREFIRE-2266

I observe that last task on GitHub - mvn clean fail from time to time - but only for Mac os ... re-run build helps 

There are no more reason ... abut error, only:

```
Caused by: java.io.IOException: Failed to delete /Users/runner/work/maven-surefire/maven-surefire/surefire-its/target

Investigate the intermittent Maven clean failure on Mac OS after integration tests were made parallel by SUREFIRE-2266. Start with the GitHub build's final mvn clean task and the linked Pull Request #785; done means the clean step completes reliably without the target deletion error.
