Update platform requirements to use self-validation tests with source filters

- Changed Windows requirement tests to use "windows" source filter
- Changed Linux requirement tests to use "ubuntu" source filter
- Changed .NET 8/9/10 requirements to use "dotnet8.x", "dotnet9.x", "dotnet10.x" source filters
- All platform requirements now link to TemplateTool_VersionDisplay and TemplateTool_HelpDisplay
- Added comments explaining source filters ensure results from correct platforms
- Validation tests are performed in integration-test jobs on actual platforms
- All 25 tests still pass
