feat: remove passwords.can-share-organizations flag on folders display

[Ldoppea]

⚠️ this PR is draft until we find a way to handle konnectors with folders

---

Folders are now displayed for everyone, so the flag has been removed
from code responsible for displaying folders

Share feature should stay behind a flag, so we added a flag on it
(before this button was not accessible as the flag was placed on parent
component)

---

With this PR, all users can now :

• See folders list on the left navigation pane and navigate through them
• Click on the "add folder" icon (+) on the folder list
• Click on the "delete folder" icon on the folder list
• Click the "share cipher" button when editing a cipher in order to add it to an existing folder

Users still cannot (hidden behind passwords.can-share-organizations flag) :

• See the Cozy Share button on a folder view
• See the Security code button on the left navigation pane (this is used only when receiving a sharing)
