- `go build` handles appending .exe to the built binary, so we need not do
it ourselves. In fact, when we did we generated a binary called
`pulumi.exe.exe` which is not what we wanted.
- Remove the development versions of the langhost and dynamic provider,
from the `<root>/node_modules/pulumi` folder. The `dist` version gets
copied into bin.
- Add the dummy_argument workaround to the dist version of the langhost.
