Ensure GPG is installed

[dmotte]

Hi, first of all thanks for creating this role! 🙂 very useful

On the first attempt it failed on my system (Debian 11) because i didn't have the gpg package installed:

TASK [alvistack.podman : apt-key add] ******************************************
FAILED - RETRYING: [default]: apt-key add (3 retries left).
FAILED - RETRYING: [default]: apt-key add (2 retries left).

Installing it with apt-get install -y gpg solved the problem. It would be nice if the role ensures this by itself :) It is as simple as adding gpg to the _apt list here: https://github.com/alvistack/ansible-role-podman/blob/master/vars/debian-11.yml#L28

IMHO, adding gpg to the _apt list is a bit overkill:

• gpg should be something generally available for your daily operational system
• ansible-role-podman and its minimal self-provisioning on localhost with molecule converge is target for simplicity, but not for OS comprehensive provisioning (it should be the duty of https://github.com/alvistack/ansible-role-bootstrap)

Anyway, I always approach https://en.wikipedia.org/wiki/Unix_philosophy as https://en.wikipedia.org/wiki/Minimalism_(computing) and https://en.wikipedia.org/wiki/Modular_programming if possible (or even say https://en.wikipedia.org/wiki/KISS_principle). Although this is just a simple fix but I will not accept it, sorry and thank you for your kindly understanding.

OK, I understand 😉 thanks a lot for your explanation
