[Do not merge] Silly change to demo preview feature

[NicolasGensollen]

This PR is a demo for the HTML preview feature.

It is not meant to be merged!

There are a few points to note:

• This does NOT work for pull requests opened from forks (so either do not fork the project, or push to the upstream remote instead of the origin remote).
• There is a first workflow called "Deploy PR previews" that runs on the PR: Once it finishes, it will post a message with a link to the preview. The link will not work immediately. You need to wait for the "deploy" workflow to run in the background before the link actually works (usually takes a couple minutes...).
• Once this is done, the link points to the preview such that you can inspect how your changes rendered without altering the main website.
• Once the PR is merged, the preview will be deleted and the modifications will be deployed as the main website.

This is a super nice tool, thanks!

Do you have an idea why the Job offers page appears all crappy in the preview but not on the published website? I have the same display on the PR #23 for the Job offers and Publications pages and so I'm not sure whether I messed something up or not...
