Affected image and tag	new one

We need an NodeJS image containing Puppeteer and Chrome to run our front-end tests.
Currently, we are using juliensnz/node which was not updated since its creation 8 months ago.

We should have 2 tags for this image:

• akeneo/node:8 based on node:8 (for Akeneo 2.3)
• akeneo/node:10 (which will also be the latest tag) based on node:10 (for Akeneo 3.x)
