[benchmarks] Disable dotnet and golang benchmarks (#34080)

This should get the benchmarks running again. The dotnet benchmark is
broken (unclear if it's still necessary), and the grpc-go benchmark
build currently fails. The go benchmark should be re-enabled when the
dockerfiles are fixed. The rest of the dotnet benchmark configuration /
artifacts should be deleted or fixed as well. @jtattermusch
