[Freebox integration] Add certificates to support italian freebox (iliadbox) #166502
Description
The problem
The integration does not work with the italian freebox pop (aka iliadbox) due to different CA certificates compared to the French version.
I could get it working by adding the certificates to HA using the additional_ca integration, so if these certificates could be added to the integration it should fix it for all italian users.
The certificates are taken from the official documentations accessed from the freebox\iliadbox local web interfaces, but I couldn't find and online source to put as a reference (they are not in the online docs, which are for the French freebox I guess).
