Build TestMVC.csproj before opening the generated-file steps.

The six files under obj/GX are not tracked and are absent in a clean checkout. video.json opens the project but does not build it before the tour runs. Add an explicit dotnet build, or move these steps after the build.

In `@v2/.tours/EndpointHelpers.tour` around lines 32 - 65, Update the
EndpointHelpers tour flow so TestMVC.csproj is explicitly built before the six
generated-file steps under obj/GX are opened. Add the build action at the
appropriate earlier point, or move those generated-file steps after the existing
build, while preserving the current file-opening sequence.
