Update handling of rules_nodejs transitive deps

BREAKING CHANGES:

rules_typescript_dependencies() will no longer install transitive dependencies of build_bazel_rules_nodejs. User WORKSPACE files will now need to install rules_nodejs transitive deps directly:

```
load("@build_bazel_rules_nodejs//:package.bzl", "rules_nodejs_dependencies")
rules_nodejs_dependencies()
```

Closes #328
