[Idea] GitHub Action for updating krew index entry?

[porridge]

Kuttl project has this hacky shell script which a release engineer has to run and then copy-paste the result into a PR in the krew repo.
Would it be possible to have a krew-index-update GitHub Action that plugin projects could use in their repos, that would automate this workflow? 🤔

Please consider setting up Krew release automation which helps you skip manually making updates to your Krew manifests on each new version and send a pull request. It’s a GitHub workflow bot that can run every time you push a new tag. Those PRs are automatically approved.
