Steps to reproduce:
On Windows (the example uses Cygwin):
1. `git clone https://github.com/fedinskiy/quarkus-test-suite -b fix/workspace-win && cd quarkus-test-suite`
2. `mvn -B -fae clean verify -pl http/http-advanced -Dit.test=DevModeWorkspaceIT -Dquarkus.platform.version=3.27.0.temporary-redhat-00003 -Dquarkus.platform.group-id=com.redhat.quarkus.platform -Dmaven.repo.local="C:\cygwin\home\hud
son\rh-quarkus-platform-3.27.0.GA-maven-repository\maven-repository" -Dts.docker-detection-enabled=false -Dquarkus.qe.framework.version=1.7.3 -Dreruns=0`

When accessing Dev UI Workspace on Windows, it doesn't show folder hierarhy, but shows full path for every file instead.
