Fix test failures by locking typescript version (#534)

- Fix test build failures by locking `typescript` version to `3.7.5` as suggested by typed-ember/ember-cli-typescript#1103
- Add `.nvmrc` file to specify `node: 10` which fixes failing `netlify` build due to `The engine "node" is incompatible with this module. Expected version ">= 10.*".`
- Also disable `no-quoteless-attributes` rule for `ember-cli-template-lint`
