Update config for Gilded Rose exercise

[fpsvogel]

Adds to config.json for the new Gilded Rose exercise:

• Contributors list
  • Reviewers of [New practice exercise] Gilded Rose #1586 plus BethanyG, who gave extensive feedback in the forum thread.
• Minimum Ruby version of 3.1
  • The tests use omitted values in hash literals, a Ruby 3.1 feature.
• In the root config.json, removes the prerequisites for Gilded Rose. This makes the exercise more easily accessible to Ruby devs who aren't already on Exercism. (If they came for Gilded Rose, did the "Hello world" exercise, and then saw that they still needed to other exercises first, they might give up.)
  • EDIT: Removed, see blow.

I also wanted to specify an icon, but the existing icons are specific to other exercises, and googling didn't turn up any suitable free icon with a permissive license. I'm not an artist, so I'll leave off the icon for someone else to contribute.

Hello. Thanks for opening a PR on Exercism. We are currently in a phase of our journey where we have paused community contributions to allow us to take a breather and redesign our community model. You can learn more in this blog post. As such, all issues and PRs in this repository are being automatically closed.

That doesn't mean we're not interested in your ideas, or that if you're stuck on something we don't want to help. The best place to discuss things is with our community on the Exercism Community Forum. You can use this link to copy this into a new topic there.

I think the removal of the prerequisites are fine. We can see how that works out.

In the root config.json, removes the prerequisites for Gilded Rose. This makes the exercise more easily accessible to Ruby devs who aren't already on Exercism.

I don't like this change. The same argument could be made for pretty much any exercise. I don't think this is a special exception. If someone doesn't want to do the prereqs we have a UI-level option for that, which is to switch to Practice Mode. Instead, we'll get newbies to Ruby trying to do it as it gets unlocked straight away. So I think this change should be reverted.

Do we need to revert this or just not accept it? I think we may not need to revert it, it does not appear to have been accepted yet (I did not merge it only approved it pending other opinions.)

Also, since this is active, we can force push without fed0cd5 being included.

Ah, I thought it was merged. Yeah, just leave that bit out please :)

As @iHiD commented, let's leave the prerequisites in. The student has a way to get around having to do the exercises for the prerequisites, and it hopefully will avoid folks trying to refactor without having a good (enough) understanding of the prerequisites.

Done!
