Rewrite apps installation script as an Ansible playbook

1.
```console
pip install ansible-core --user
```
2. create an inventory file with a `localhost` entry in it with `connection=local` param
3. create a playbook `install-apps.yml`
it'd look smth like
```yaml
- name: Install OS-level apps
hosts: all
become: yes
tasks:
- name: Configure repositories
apt_repository:
...
- name: Install apps
apt:
name:
-
-
...
```
4. The invocation would look like:
```console
ansible-playbook -i inventory -K install-apps.yml
```
