playground: parameterize GO_VERSION in Dockerfile

This will allow us to specify a GO_VERSION at build time.

Bumps GO_VERSION to go1.12.6.

Moves BUILD_DEPS install step before GO_VERSION which improves
intermediate step caching during development.

Verified locally with:
- docker build --build-arg GO_VERSION=go1.12.6 (and others)
- Ran fmt.Println(runtime.Version()) in the playground to verify the
version changed.

Updates golang/go#32606
