Update docs/installing.md and docs/quick-start.md: mention "make roles"

This commit adds mentions to "make roles" and a note about the preference of ansible-playbook commands over the just "recipes".

quick-start.md intends to be referred by those who have never used the playbook to set up a server, so it is safer to regard that it is not clear to them what exactly the just "recipes" are made of, ie. it takes some time and experience until someone understands simplicity of them. For beginners, I believe that we should prefer the basics over simplicity, from the educational point of view.

If someone feels tired of using the same command repetitively, then the person will have been already well accustomed to the way how the playbook works and how the server is supposed to be maintained, and the person is "qualified" to use the just "recipes", and should be able to use them with confidence, distinguishing the playbook tags from the "recipes", for example, from "just install-all" and "ansible-playbook -i inventory/hosts setup.yml --tags=install-all". Such level of familiarity and experience should not be expected on the quick start guide.

 ## Update Ansible roles

+Before installing, you need to update the Ansible roles that this playbook uses and fetches from outside.
+
+To update them, run `just roles` (or `make roles` if you have `make` program on your computer instead of `just`).
 
 `just roles` is a shortcut (a `roles` target defined in [`justfile`](../justfile) and executed by the [`just`](https://github.com/casey/just) utility) which ultimately runs [agru](https://github.com/etkecc/agru) or [ansible-galaxy](https://docs.ansible.com/ansible/latest/cli/ansible-galaxy.html) (depending on what is available in your system) to download Ansible roles. If you don't have `just`, you can also manually run the `roles` commands seen in the `justfile`.
 
-There's another shortcut (`just update`) which updates the playbook (`git pull`) and updates roles (`just roles`) at the same time.
