Add detailed individual test result reporting to GitHub Actions workflows

[Copilot]

• Analyzed repository structure and current GitHub Actions workflow
• Identified that the workflow runs multiple test suites (Unit, Integration, and various persistence provider tests)
• Confirmed that current test output is minimal using dotnet test --verbosity normal
• Research available test result reporting formats for detailed GitHub Actions output
• Implement test result reporting improvements
• Add test result artifacts/reporting
• Update GitHub Actions workflow to show detailed individual test results
• Test and validate the enhanced reporting works
• Clean up artifacts and add proper gitignore rules
• Fix deprecated actions/upload-artifact version (v3 → v4)

Summary of Changes

Enhanced GitHub Actions Workflow (.github/workflows/dotnet.yml):

• Detailed Console Output: Changed verbosity from normal to detailed for all test jobs
• TRX Test Results: Added TRX logger to generate structured XML test result files
• Test Reporter Integration: Added dorny/test-reporter@v1 to display test results in GitHub UI
• Test Artifacts: Added artifact upload for all test result files using actions/upload-artifact@v4
• Individual Job Coverage: Enhanced all 9 test jobs (Unit, Integration, MongoDB, MySQL, PostgreSQL, Redis, SQLServer, Elasticsearch, Oracle)

New Features:

1. Individual Test Visibility: Each test case shows pass/fail status, execution time, and detailed error information
2. Structured Test Data: TRX files contain comprehensive test metadata including stack traces
3. GitHub UI Integration: Test results appear in PR checks with detailed failure information
4. Downloadable Artifacts: Test result files available for download from each job
5. Enhanced Debugging: Detailed console output and error messages for faster issue identification

Documentation (docs/enhanced-test-reporting.md):

• Complete guide to the enhanced test reporting features
• Examples of before/after output formats
• Explanation of TRX file structure and benefits
• Instructions for accessing test results in GitHub UI

Infrastructure:

• Added test-results/ to .gitignore to prevent test artifacts from being committed
• Cleaned up temporary test files
• Updated to use actions/upload-artifact@v4 (latest stable version)

The enhanced workflow will provide detailed, individual test results as requested, making it much easier to identify and debug test failures in GitHub Actions.

Original prompt

I want to be able to see the detailed, individual test results of tests that are run be github workflows.

Fixed in commit c764721. Updated all 9 occurrences of actions/upload-artifact@v3 to @v4 in the workflow file to resolve the deprecation issue.
