Image Card for social media preview of the repo

[lorepirri]

Problem

As the repository of the tupuapp is from yesterday open source, it would be nice to have a nice brand design around it (as we have for the website).

It would be nice to have a card for the social media preview image.

Feature Description

It's just a nice to have, and this is a placeholder.

• create an image card for the tupuapp repository’s social media preview
  • take inspiration from https://www.tupu.io/
  • the image should be at least 640×320px (1280×640px for best display)
  • here the GitHub template: https://github.com/tupuio/tupuapp/settings/og-template
  • where to set it: https://github.com/tupuio/tupuapp/settings
