[federation] Remove redundant default filter in hook_controlplane_config

Address non-blocking review suggestion from evallesp on ci-framework
PR #3766.

Remove the redundant trailing | default('custom-ca-certs', true) from
the _federation_ca_bundle_secret_name fact. The preceding
cifmw_custom_ca_certs_secret_name | default('custom-ca-certs', true)
already guarantees a non-empty value, making the outer default a no-op.
