artifacthub: Move to folder based releases

[illume]

• Converted 11 plugins (ai-assistant, cert-manager, example-change-logo, flux, keda, knative, kompose, minikube, opencost, radius) from flat structure to versioned folders
• Created version folders for all historical releases by extracting artifacthub-pkg.yml and README.md from each release tag in git history
• Added changes field to each artifacthub-pkg.yml parsed from GitHub release notes
• Removed kubeflow artifacthub files because it causes an error

---

Just overwriting the file removes the old releases. The "proper" way is to do a folder for each release. It's documented here: https://artifacthub.io/docs/topics/repositories/headlamp-plugins/

Like how the karpenter plugin does it:
https://github.com/headlamp-k8s/plugins/tree/main/karpenter

Notice how there are versions on the Karpenter one?

https://artifacthub.io/packages/headlamp/headlamp-plugins/headlamp_karpenter

But not the flux plugin on artifacthub?

Without doing folder the previous release goes away for people.

Pull request overview

This PR restructures ArtifactHub package metadata for multiple Headlamp plugins to use folder/version-based release manifests, adding per-version artifacthub-pkg.yml files (with changes entries) and per-version README.md files, and removing the legacy top-level Flux ArtifactHub manifest.

Changes:

• Add/extend changes: entries in multiple per-version artifacthub-pkg.yml manifests.
• Add per-version README.md files across plugins to support folder-based ArtifactHub releases.
• Remove the legacy flux/artifacthub-pkg.yml in favor of versioned manifests under flux/<version>/.

radius/0.1.1/artifacthub-pkg.yml:11

• There’s an extra space before the final period after the Radius link (...radapp.io/) .), which will render oddly in ArtifactHub’s changelog. Remove the stray space so the sentence reads cleanly.
