Pretty straightforward, using deeplinks similarly to #126 , we should list all the social links of all the clubs before, can we obtain this from the Amicale or just search for them one by one

The data is provided by the API. See Club type in ClubListScreen.

Note that the instagram properties are sometimes the account name (club_name or @club_name), sometimes the https url (sometimes with unsanitize query parameters), and sometimes null. It might be better to standardize this in the database, or at least in the API data. @baptistereb What do you think ?
