Updates the NodeJS version to the latest stable version at the time of writing (v10.16.0). We need to update our image to use a minimum NodeJS version of v10.15.0 because new CLI apps automatically install a non-locked version of selenium-webdriver that now requires NodeJS >= 10.15.0 since the latest release of 17th June 2019 (4.0.0-alpha.3).

Encryption
Based on https://github.com/circleci/encrypted-files
In the CircleCI web UI, we have a secret variable called KEY
https://circleci.com/gh/angular/angular/edit#env-vars
which is only exposed to non-fork builds
(see "Pass secrets to builds from forked pull requests" under
https://circleci.com/gh/angular/angular/edit#advanced-settings)
We use this as a symmetric AES encryption key to encrypt tokens like a GitHub token that enables publishing snapshots.
To create the github_token file, we take this approach:
- Find the angular-builds:token in http://valentine
- Go inside the CircleCI default docker image so you use the same version of openssl as we will at runtime:
docker run --rm -it circleci/node:10.12 - echo "https://[token]:@github.com" > credentials
- openssl aes-256-cbc -e -in credentials -out .circleci/github_token -k $KEY
- If needed, base64-encode the result so you can copy-paste it out of docker:
base64 github_token
