fix: apply version override to build step instead of pack step

MinVer calculates version during the build step, not the pack step.
Using dotnet pack --no-build with -p:Version doesn't work because
the assemblies are already built with the wrong version.

This fix moves the -p:Version parameter to the dotnet build command
so that MinVer is properly overridden during compilation.
