[Bug]: JUnit `junit-output-path` not working properly

[ky0jr]

Description

The junit-output-path command line argument is not working.
It looks like _outputPath is not checked to see if it has already been assigned.
Using env JUNIT_XML_OUTPUT_PATH is the workaround for now,

Expected Behavior

The junit-output-path argument sets the expected JUnit output path properly.

Actual Behavior

The JUnit report is generated in the default path.

Steps to Reproduce

1. Explicitly enable JUnit reporter with env TUNIT_ENABLE_JUNIT_REPORTER (pwsh $env:TUNIT_ENABLE_JUNIT_REPORTER=1)
2. Run dotnet test --junit-output-path ".\results\junit.xml"
3. The xml file is in MyApp.UnitTests/bin/Debug/net10.0/TestResults/MyApp.UnitTests-junit.xml
