Bump element version

This is a security relevant update

Update Ntfy 1.27.2 -> 1.28.0

Update Element 1.11.5 -> 1.11.6

This mostly fixes `key-order` warnings around
`block` statements.

Update Prometheus Node Exporter 1.3.1 -> 1.4.0

If someone is using Dendrite and enabling Grafana, we'll no longer
download Synapse dashboards.

If someone is not using node-exporter, we'll no longer download node
exporter dashboards.

This is consistent with what all other roles do. If someone includes a
role, the assumption is that they want its functionality enabled.

The playbook distribution then disables components via
`group_vars/matrix_servers`. We've always had `matrix_grafana_enabled: false`
there, so flipping the in-role `_enabled` flag to `true` does not change
anything for playbook users. Users who import the roles individually in
their own other playbooks (and who don't use `group_vars/matrix_servers`)
may observe a change in the defaults with this.

Using `matrix_synapse_*` variables within the `matrix-grafana` role
is not a good practice.

We now have a `matrix_grafana_default_home_dashboard_path` variable
with a good universal default value and we override it via
`group_vars/matrix_servers` based on enabled components, etc.

This is a better fix for https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2133

We shouldn't be using it in the role (`tasks/setup.yml`) without
defining at least some default value in the role itself.

We've always had the override in `group_vars/matrix_servers`,
so the variable was essentially defined (at the playbook level), but
that's not the right way to do things.

Do not restart postmoogle during installation

Reason: during a fresh install, when there is no synapse yet, systemd unit fails to start, thus whole play fails
