Suppression du `keyserver_warning`
Le log de matrix_synapse_1
renvoie :
Starting synapse with args -m synapse.app.homeserver --config-path /data/homeserver.yaml
This server is configured to use 'matrix.org' as its trusted key server via the
'trusted_key_servers' config option. 'matrix.org' is a good choice for a key
server since it is long-lived, stable and trusted. However, some admins may
wish to use another server for this purpose.
To suppress this warning and continue using 'matrix.org', admins should set
'suppress_key_server_warning' to 'true' in homeserver.yaml.
