### Bug description

I made a GitHub action to update https://rlille.fr website built with Quarto.
I wanted to check the latest updates in Quarto.
It appears from the automatic PR (https://github.com/RLille/rlille.fr/pull/8), that now `og:description` and `twitter:description` content are truncated for some reason (It's only 43 characters).

You can see the file in the PR below
