Two errors from PR #391813 manifest validation (build 349844): 1. 'The schema header URL does not match the expected pattern.' I used raw.githubusercontent.com URLs, but the validator wants the aka.ms short URLs that the official winget-bot uses. Updated all 3 files to https://aka.ms/winget-manifest.*.1.12.0.schema.json 2. 'Silent and SilentWithProgress switches are not specified for InstallerType exe.' TrianglesQt installer is built with NSIS (see build-all.yml 'Install NSIS via MSYS2' step + mingw-w64-x86_64-nsis package). NSIS silent flag is /S. Added both Silent and SilentWithProgress. Closes superseded PR microsoft/winget-pkgs#391813 (same Manifest-Validation-Error).
