fix(scripts): enhance NuGet push handling for Linux environments

Update build-dist.sh to improve NuGet package publishing on Linux by introducing a check for the dotnet CLI, which avoids SSL issues with nuget.exe. Adjust documentation to clarify the use of dotnet for pushing packages and the limitations of nuget.exe on Linux.

 Notas
   - Compilación: msbuild (preferido) o xbuild. En Ubuntu instale mono-complete del repo oficial Mono.
-  - En Linux no use 'nuget restore' (SSL Mono + MSBUILD0004); use restore-packages.sh.
+  - En Linux: nuget pack/push con nuget.exe (Mono) falla SSL; pack usa rutas del nuspec, push usa dotnet nuget push.
   - nuget sign (Author Signing) requiere Windows; aquí se publica unsigned (Repository Signing).
   - Si empuja el tag, CI puede duplicar NuGet/GitHub Release — use una vía u otra.
