Make #id URLs work by setting the location.hash again after all cells are rendered

[fonsp]

Now you will be able to share a URL like:

https://plutojl.org/en/docs/abstractplutodingetjes/#c3e83475-6ab0-4aa8-9a57-c2f25772cc75

Before this PR, this does not work because cells are rendered with a delay, and the UA tries to scroll to the element quickly after the page got loaded.

This PR also makes this URL work:

https://plutojl.org/en/docs/abstractplutodingetjes/#possible_values

By giving all Docs.binding displays the id of the variable name.

Unfortunately this does not work with Chrome's "Copy link to this selection" feature, because the special chrome hash (#:~:text=.-,Add%20a%20comment,-Comment) is hidden from the window.location.hash, so there's nothing we can do about that.
