remove obsolete config entry "federation_certificates" (#2318)
* Remove all federation_certificates occurencs

This configuration value has not been used since 2019 apparently, and indeed
it is never really used in the code base. So remove all traces of it from
the various configuration files.

Also remove the unused variable FederationCertificatePaths

Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de>

* setup/config/config_test.go: remove federation_sender config snippet

The federation_sender: section was folded into the federation_api some
time ago, and this seems to be the only leftover in the code base.
So remove it.
