Update configuring-playbook-synapse.md

This change adds a section that lets the reader know that it is possible to enable synapse metrics and references the relevant documentation.

It aims to be short and concise, leaving the specifics to the referenced documentation, while still giving the reader a good idea of what it is and what it is for.

fix(traefik): Ignore federation endpoint if entrypoint with port already exists

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2621

Fix CHANGELOG.md typo

If Traefik is used, these are not Wanted services.

The playbook auto-generates these passwords, so there's no need
to ask people to do it manually.

People who need to time things should do it themselves, explicitly.
Forcing `time` on people is a little rude.
