how to test krew-index manually?

[Slach]

tested manually with

docker run --rm -v ./.krew/tail.yaml:/tmp/template-file.yaml ghcr.io/rajatjindal/krew-release-bot:v0.0.46 krew-release-bot template --tag v0.17.2 --template-file /tmp/template-file.yaml 1>/tmp/tail.yaml

go install sigs.k8s.io/krew/cmd/validate-krew-manifest@latest

~/go/bin/validate-krew-manifest -manifest /tmp/tail.yaml
