Web app: better promote citation interface in browse views
Currently, the interface to get the Software Heritage persistent identifiers of currently browse objects in the web application is reachable from the 'Show identifiers' entry in the 'Actions' menu.
This feature is really important as it gives the user a sustainable way to cite and reference the archive content. In the current state of the browse web application, it is not straightforward to use as it requires a couple of navigation steps for the user before displaying it, thus he will prefer to copy/paste the current url in the adress bar of his browser.
We should better promote that citation feature in the web application interface by emphasizing it in a different way in all the swh-web/browse views.
