Upgrade Node.js in the PHP container

[michaelcasey316]

Magneto Cloud Docker includes a Node.js installation as part of the CLI containers. This can be seen here: https://github.com/magento/magento-cloud-docker/blob/develop/images/php/cli/Dockerfile#L15

However, the problem is that it installs Node.js 8, which no longer receives security updates according to https://nodejs.org/en/about/releases/

We need to change this to a supported version of Node.js, such as version 10 or higher. We could also use Node Version Manager (https://github.com/nvm-sh/nvm) to simplify version selection.

Internal ticket reference: MCLOUD-5586

Preconditions

1. Install Magento Cloud Docker
2. Build the configuration

Steps to reproduce

1. Run docker-compose run deploy node -v from your project folder.

Expected result

1. The version shown is supported according to https://nodejs.org/en/about/releases/

Actual result

1. Version 8.x is shown, which is unsupported.
