docs: Confusion with stable-0.x docs

[superstes]

What is the issue ?

When users search ansible ara configuration in search-engines like Google - only the old stable-0.x documentation shows up: https://ara.readthedocs.io/en/stable-0.x/configuration.html

This can be very confusing to new users as these config-settings do partially not work with the latest version.
Example: ignore_facts vs ignored_facts

What should be happening ?

Is the old documentation still relevant? As far as I see the old branch has not had changes since 5 years.
Maybe just delete that old documentation-revision?
Or put a yellow banner on top to inform users that this is not the documentation for the latest version?

Also: Maybe add a keyword like ARA client configuration to the current configuration page so it gets picked-up easier by search-engines: https://ara.readthedocs.io/en/latest/ansible-plugins-and-use-cases.html

Hi and thanks for the issue.

I understand the sentiment though until somewhat recently there were still users of 0.x out there.
It would be fair to retire it by now, they have long diverged and I haven't supported 0.x in a long time.

I'll leave this issue up and we can take care of it.
I have no control over the SEO and search engine results though :p
