Redesign home jo

[garronej]

• I implemented Mark's design for the home page. figma
• I renamed acceuil to home.
• I got rid of Suspense in favour of a more traditional approach for loading async data in react component. ( Suspence is cool but not a stable feature yet)
• I used YAML instead of JSON to populate the page. Once merged the following env should be edited REACT_APP_HOMEPAGE_URL=https://git.lab.sspcloud.fr/innovation/plateforme-onyxia/services-ressources/-/raw/master/pages-content/home.yaml
• I encourage everyone to use YAML to JSON when working on pages that are populated from an external resource file. It generates types definitions from a YAML (or JSON) files. It enable to spot typos and inconsistencies in the data structure early on.
• The page is somehow responsive, see result here

Unfortunately it was not possible to use material UI and respect Mark's design at the same time so I had to write custom CSS.

Of course feel free to change the wording by editing home.yaml especially for the third section that wasn't discussed in details.

Sorry for the large commit's Diff.
