Fix path handling in test files for cross-platform support

Updated `CycloneBomProcessorTests.cs`:
- Removed trailing backslash from `sourcePath`.
- Used `Path.GetFullPath` and `Path.Combine` for `output.json` path.

Updated `CreatorHelperTest.cs`:
- Appended `Path.DirectorySeparatorChar` to `localPathforDownload`.
