Edit descriptions about installation of components (#3842)
* Replace installation command shortcut for the "just" program with the most conservative raw ansible-playbook command

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.

* Add comments about using setup-all instead of install-all

* Add description about shortcut command with the "just" program to the ansible-playbook command with "setup-all" and "start" tags

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

* Update raw ansible-playbook command to have it do what "just install-all" or "just setup-all" does

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

* Remove "ensure-matrix-users-created" from the raw ansible-playbook command which does not need it

Also: update the "just" recipes accordingly. "just install-all" and "just setup-all" run "ensure-matrix-users-created" tag as well, therefore they need to be replaced with "run-tags" recipes to skip "ensure-matrix-users-created"

* Update docs/configuring-playbook-etherpad.md: add ensure-matrix-users-created to the raw ansible-playbook

Signed-off-by: Suguru Hirahara <acioustick@noreply.codeberg.org>

* Add description about "ensure-matrix-users-created" and create a list with description about shortcut commands with "just"

This commit also fixes list item capitalization and punctuation.

* Update docs/configuring-playbook-matrix-corporal.md and docs/configuring-playbook-email2matrix.md: adopt common instructions

Signed-off-by: Suguru Hirahara <acioustick@noreply.codeberg.org>

* Replace "run the installation command" with "run the playbook with tags"

Now that shortcut commands for the "just" program are displayed along with the existing "installation command", this commit replaces "run the installation command" with "run the playbook with tags" in order to prevent misunderstanding and confusion.

* Remove redundant blank lines

* Update docs/configuring-playbook-alertmanager-receiver.md: remove the direction to proceed to Usage

Such a kind of direction is not used on other documentation, so it should be fine to just remove it.

# Maintenance and Troubleshooting
## How to see the current status of your services
You can check the status of your services by using `systemctl status`. Example:
```sh
sudo systemctl status matrix-synapse
● matrix-synapse.service - Synapse server
Loaded: loaded (/etc/systemd/system/matrix-synapse.service; enabled; vendor preset: enabled)
Active: active (running) since Sun 2024-01-14 09:13:06 UTC; 1h 31min ago
```
Docker containers that the playbook configures are supervised by [systemd](https://wiki.archlinux.org/title/Systemd) and their logs are configured to go to [systemd-journald](https://wiki.archlinux.org/title/Systemd/Journal).
To prevent double-logging, Docker logging is disabled by explicitly passing `--log-driver=none` to all containers. Due to this, you **cannot** view logs using `docker logs`.
To view systemd-journald logs using [journalctl](https://man.archlinux.org/man/journalctl.1), run a command like this:
```sh
sudo journalctl -fu matrix-synapse
```
## Increasing Synapse logging
Because the [Synapse](https://github.com/element-hq/synapse) Matrix server is originally very chatty when it comes to logging, we intentionally reduce its [logging level](https://docs.python.org/3/library/logging.html#logging-levels) from `INFO` to `WARNING`.
If you'd like to debug an issue or [report a Synapse bug](https://github.com/element-hq/synapse/issues/new/choose) to the developers, it'd be better if you temporarily increasing the logging level to `INFO`.
Example configuration (`inventory/host_vars/matrix.example.com/vars.yml`):
```yaml
matrix_synapse_log_level: "INFO"
matrix_synapse_storage_sql_log_level: "INFO"
matrix_synapse_root_log_level: "INFO"
```
Re-run the playbook after making these configuration changes.
## Remove unused Docker data
You can free some disk space from Docker, see [docker system prune](https://docs.docker.com/engine/reference/commandline/system_prune/) for more information.
```sh
ansible-playbook -i inventory/hosts setup.yml --tags=run-docker-prune
```
The shortcut command with `just` program is also available: `just run-tags run-docker-prune`
