[documentation] Add `ansible.posix` and `community.general` to the requirements

[b-]

Hey there,

I think this is a new change (for some definition of "new"), but when I installed Ansible by way of python3 -m pip install ansible in a venv it did not automatically install the ansible.posix or community.general collections. I wonder if they're moving to something closer to ansible-core for all new installs, or something? Or maybe they moved some modules out from builtin or something? I'm not sure, I'm pretty new to Ansible.

Your role as well as Jeff Geerling's NTP role require either or both of those collections. I didn't dig too deeply into what exactly, so I don't know what the best way to do this would be.

Would it make any sense to add your own requirements.yaml (or even maybe requirements.example.yaml) to the repository?

That seems kind of weird. I haven't personally kept myself up to date with how collections are being handled in the ecosystem, but on a quick cursory check, I grabbed the tarballs from PyPi:

[lae@sumire tmp]$ tar tvf ansible-7.5.0.tar.gz | grep -c ansible/posix
307
[lae@sumire tmp]$ tar tvf ansible-8.0.0a2.tar.gz | grep -c ansible/posix
307
[lae@sumire tmp]$ tar tvf ansible-8.0.0a2.tar.gz | grep -c community/general
3571
[lae@sumire tmp]$ tar tvf ansible-7.5.0.tar.gz | grep -c community/general
3571

Seems like the collections are in the Ansible package?

I think that's my mistake, I thought I was in my venv but I was not, and somehow I had a globally-installed Ansible that was just plain incorrect. Forgive me!
