fix: dotnet test bug

[Saksham-Sirohi]

Summary

This PR fixes the failing test in test/test_scanner.py caused by recent merges of clang and .NET-related changes. The test was asserting that clang should not be present, which led to unintended failures. This update ensures that the test properly accommodates clang detection while still verifying the .NET package.

Changes Introduced

Fixed Test Failures:
Updated test_data/dotnet.py to account for clang detection in the .NET package check.
Adjusted assertions to reflect the expected behaviour after recent merges.

Ensured Stability of Tests:
Verified that the updated test runs successfully with all expected inputs.
Re-ran all relevant test cases to confirm no regressions.

Compatibility:
No breaking changes; ensures the test correctly adapts to recent code updates.

Checklist:

• Code follows project coding standards.
• All relevant tests pass successfully.
• Verified no unintended side effects from the fix.

Steps to Test:
Run the following command to validate the fix:
LONG_TESTS=1 pytest test/test_scanner.py

Related Issues:

Fixes #4841

Additional Notes:
This fix ensures that test logic aligns with recent clang-related changes 🚀.

Thank you! I imagine a lot of folk will be happy to have the tests behaving again, but especially me since checking each PR to make sure it was only the expected test that failed can be a huge pain!

Merge time now. There's a weird failure happening on windows, but it doesn't look related to this PR. I'll keep an eye on it while i work on other code review today.
