docs: update dnf config-manager usage

[bschaatsbergen]

Closes #35979

In Fedora Linux 41 which uses DNF5, backward compatibility with DNF4 was intentionally broken. The dnf config-manager now uses new sub-commands, like addrepo, for adding repositories.

Since F41 is the latest supported Fedora Linux release, this PR proposes updating the instructions to reflect DNF5 installation.

• See DNF config-manager Plugin rpm-software-management/dnf5#405 which states the maintainers broke DNF4 backwards compatibility intentionally in DNF5.
• See for a cross-reference documentation fix in the Fedora docs: https://pagure.io/fedora-docs/quick-docs/pull-request/783

This is a fair point but I think we need to consider the wider perspective, which is that this is only one of many places where such docs exist.

https://developer.hashicorp.com/terraform/cli/install/yum

I'm not even sure where exactly do we link from to that page.

What is IMHO more impactful and visible place which will certainly need updating is https://developer.hashicorp.com/terraform/install which I think is using a shared component between all product sites.

All that is to say, given that the installation instructions are pretty much the same for all products I'm not sure there is much value in maintaining dedicated (Terraform specific) pages like these at all?

cc @hashicorp/terraform-education Any opinions or ideas on this topic?

Thanks for tagging us into this interesting one! ✨

https://developer.hashicorp.com/terraform/cli/install/yum

I'm not even sure where exactly do we link from to that page.

So this page is live, but we currently hide it in the sidenav, so folks can only find it by entering the URL. I think we can honestly just remove the page at this point, and redirect to the main Terraform installation docs as you suggested, Radek.

I'll follow-up with my team on how we can update this guidance in the main Terraform installation docs (https://developer.hashicorp.com/terraform/install).

However, I do think we should merge this to fix the Stacks CLI article. While Stacks are in public beta we are grouping all the pages together including the TFStacks CLI reference and installation page. Once we GA this will live somewhere else, but for now we should use Bruno's suggestion to update it where it is if that helps folks.

@rkoron007 Sounds good to me, as long as you keep track of this somewhere.
