Since "just install-all" or "just setup-all" invokes "ensure-matrix-users-created" as well, it needs adding to the raw ansible-playbook command.

It also explains difference between "just install-all" and "just setup-all" recipes. The explanation is based on docs/playbook-tags.md

This commit replaces installation command shortcut ("recipe") for the "just" program with the raw ansible-playbook command, so that the shortcut will be added to it later. The command is so conservative that failure of the command will mean something is clearly broken.

* Update docs/configuring-playbook-bridge-appservice-kakaotalk.md: fix the header for adjusting the playbook configuration

* Move sections "Set up Double Puppeting" under "Usage" as subsections for mautrix bridges and appservice kakaotalk

The changes in this commit reflect double puppeting configuration flow. Since the docs claim that double puppeting can be set up after enabling bridges by chatting with the bridge's bot, the explanation about double puppeting may well be placed under "Usage" as subsection.

* Remove notes about setting up double puppeting manually

Since this method is explained after configuring bridges, those notes are no longer necessary.

* Update docs for mautrix and kakaotalk bridges: add prerequisite(s) section for instructing to install Appservice Double Puppet and/or Shared Secret Auth service

* Replace "Enabling Appservice Double Puppet" with "This"

Enabling Appservice Double Puppet is contrasted with "Enabling double puppeting by enabling the Shared Secret Auth service", therefore it can be just called as "this" if Shared Secret Auth service is not mentioned below.

Overall the playbook uses the expression "Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:" with the heading "Adjusting the playbook configuration" for sections to explain what to be added as variables

Shared Secret Auth double puppeting still works for this bridge, but
is deprecated and will go away in the future.

This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.
