What:
This PR updates the footer "Follow Us" logo on the OpenFoodFacts website to reflect the recent rebranding of Twitter to X. The old Twitter logo has been replaced with the new X logo, ensuring that the footer is aligned with the current branding of the platform.

Changes:

• Replaced the Twitter logo in the footer with the new X logo.
• Updated the link to point to https://x.com/openfoodfacts instead of https://twitter.com/openfoodfacts.
• common.pot and en.po files changed too.

How to Test:

1. Go to any page on the OpenFoodFacts website (such as the homepage or product page).
2. Scroll down to the footer and locate the "Follow Us" section.
3. Verify that the X logo is now visible instead of the old Twitter logo.
4. Ensure that clicking the X logo redirects to the OpenFoodFacts X profile: https://x.com/openfoodfacts.
5. Check that the footer displays correctly on both desktop and mobile devices.

• The new X logo was sourced from (https://fr.m.wikipedia.org/wiki/Fichier:X_logo_2023.svg).

• Only the logo and associated link were updated; no other changes were made to the footer layout or functionality.
