New newsletter design

[nicolaskempf57]

Fixes datagouv/data.gouv.fr#1633

[maudetes]

Thank you for this new footer version ✨

Things I see that differ between udata-front and front-end:

• logo twitter
• Open data h3 size is not similar (due to datagouv components override?)
• Follow us on social media is not vertically aligned with Subscribe to our newsletter
• See our next events button is blue or black
• data.gouv.fr logo size
• Data catalog does not exist in front-end
• A product of the Direction Interministérielle du Numérique(DINUM). horizontal alignment differs between the two (maybe due to language picker missing?)
• Licenses is to be preferred instead of Licences
• horizontal spacing between Licenses and Terms of use

• Data catalog does not exist in front-end

I added a csvDatasetId runtime variable to pass the id, to match the udata-front side

• A product of the Direction Interministérielle du Numérique(DINUM). horizontal alignment differs between the two (maybe due to language picker missing?)

Indeed, this is the cause of this misalignment
