feat: add demo env

#28 (closed)

Two solutions are possibles

1. deploy with open shift

https://ecolyo-rec.apps.grandlyon.com/

Requires :

• k8s
• Dockerfile, building and pushing an image

takes ~1min

2. deploy with gitlab pages

https://web-et-numerique.forge-pages.grandlyon.com/factory/llle_project/ecolyo_landing_page/

• easy

Takes ~30s

I would opt for this solution
