Provide Jenkins slave image for Node

Summary:
The PHP node is a little old, and initially prepared for Laravel
purposes.

We provide a more up-to-date generic-purpose clean Node image.

The first use case is to generate OpenAPI/Swagger documentation.
As such, the image contains Spectacle.

Ref T1464

Test Plan: Build image, use it for docker-registry-api-doc Jenkins job (Node part).
