fix: Run Ansible versions validation tasks on check mode

[Al-thi]

Proposed changes

fix #840

Since a6712e3, ansible and jinja versions are validated to ensure supported versions are used.
This validation is done by delegating command tasks to localhost, and parsing the standard output of the executed commands, e.g. ansible --version.

The ansible.builtin.command module is not run when in check mode, causing the variable which is supposed to get the result of the command to be empty, resulting in an error message in the following tasks that parse these result variables.

This commit ensures the command tasks are run even in check_mode. As they do no modification on localhost, this is not dangerous.

Thanks for the PR! I feel like we should probably leave both the entire jinja2 and collections checks out of check mode? There's not much to assert in the assert task if we skip the tasks to the get the info we need to make the assertions.

Mmmm i'm not sure about this. My commit is not to skip the validation tasks, but to run them correctly even in check-mode. Is this not what is best ? Thank you

You are absolutely right! I glanced over the PR first thing in the morning before I caffeinated myself and I totally misread the text. One last thing, can you update the changelog?

Haha no problem, I know the feeling.

Done, I hope that's OK :)
