preview action not working

[miselico]

The action which is used to preview changes from pull requests is no longer working.
It appears the deploy key does no longer give access. Has it been removed from https://github.com/Knowledge-Graphs-Book/HTML-Book-staging ?

I do not know. When pushing things to a new branch, I realised there was something wrong that I could not understand and I pushed a minor change to an auxiliary file directly to the main branch and it worked. But I don't want to push things that can affect the main book directly to the main branch so my last pull request is waiting for validation. Then I only submitted issues, waiting for some more insights to decide how to propose further updates.
