matrixsynapse: Explicitly set the trusted key server to matrix.org
The following message is shown when Matrix Synapse server is started.

"""
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.
"""

Explicitly configure the server to use matrix.org as the trusted key server to
avoid the warning. The value can be set to empty list of servers, however, our
users are served best by this default.

Tests:

- On a testing container, when patch is applied after Matrix app installation,
the configuration file is updated.

- After the configuration is updated the warning is removed during Matrix
Synapse startup.
