Migrate from MSBuild to dotnet build and test, and disable NuGet pack…

…age restore

In light of recent changes in software development practices, we have migrated the build and test scripts in appveyor.yml from MSBuild to dotnet. The "msbuild" command has been replaced with "dotnet build" and "vstest.console" with "dotnet test". Additionally, the environment variable for NuGet package restore has been set to false in both appveyor.yml and SubtitleEdit.csproj files. By not restoring packages on each build, we reduce network traffic and improve build performance.
