Fix Windows build by upgrading console 0.5 -> 0.7.

[repi]

Was getting compile errors in tower-grpc-interop when running the tests due to the winapi version used by the older console crate. So upgrade to the latest version which just worked.

error[E0531]: cannot find unit struct/variant or constant `VK_BACK` in module `winapi`
