Add a small tip to maintenance-migrating.md

matrix-synapse/tasks/setup_uninstall.yml would previously not run unless

`spam_checker` has been deprecated for quite a while.
While it still probably works and while newer versions of
mjolnir-antispam still use it, we should switch to the new API.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2846
