Created by visualize link points to Chart

[noahonyejese]

Closes #2031

What's new?
This PR Now navigates users to the corresponding Chart when clicked on the "Created by visualize.admin.ch" section in the footer, like this users can benefit from quick chart creation & potentially starting out with a more established Chart.

How to test

1. Go to this Link
2. Create a new Visualisation
3. Publish Visualisation
4. Memorize last part of the URL (e.g Xx3-xKHq9K2G) -> this is necessary because we only support production charts
5. Click the "Created by visualize.admin.ch"
6. See how it navigates to the same Chart (See url) ✅

---

@bprusinowski please let me know if it makes sense here to make the URL dynamic or if I should keep it only for visualize.admin.ch, Vercel also has a URL called VERCEL_URL we could be using this for cases like these. Let me know what you think. 👀

Thanks for the enhancement @noahonyejese i believe this will need to be on TEST before it can be tested. I tested in the PR with this chart: https://visualization-tool-git-fix-visualize-link-to-public-charts-ixt1.vercel.app/en/v/cZhzddlopnkb?dataSource=Prod the target link i see is https://visualize.admin.ch/en/v/cZhzddlopnkb (which looks correct - as this suggests it points to a chart and not the landing page) but when I click the link I get a 404 - this page could not be found.

Thanks @noahonyejese, LGTM!

I think it would be good to consider two comments related to state.key, but other than that really nice :)

I wouldn't introduce dynamic URLs, it would only make it work for testing environments, which aren't supposed to hold shareable charts anyway.

We'd also potentially introduce another dependency to Vercel, which I don't think we really need 👍
