🐛 Pin document is available on subdocs

Bug Report

Problematic behavior
When I'm on a subdoc and I click on the doc menu I see that I can pin the document. When I click on it, the document is not pinned.

Expected behavior/code
I shouldn't see the pin option in the dropdown.
Or if I see it it should pin the subdoc in the left panel in the favourite section. @rl-83 what do you think ?

Steps to Reproduce

1. Do this...
2. Then this...
3. And then the bug happens!

Environment

• Docs version: 3.7
• Instance url: docs.numerique.gouv.fr

Possible Solution

Additional context/Screenshots

As talk with @rl-83, a child doc should appear in the favorite list if pinned, so it is a backend bug actually.

@AntoLC front-end you mean right ? The pin is saved in the db so backend appears to be working fine.
