For all cert-manager versions from `v1.8.0` and later, cert-manager container images are signed and verifiable using [`cosign`](https://docs.sigstore.dev/cosign/overview).

The cert-manager project publishes the following container images on Quay:

- `quay.io/jetstack/cert-manager-controller`
- `quay.io/jetstack/cert-manager-webhook`
- `quay.io/jetstack/cert-manager-cainjector`
- `quay.io/jetstack/cert-manager-acmesolver`
- `quay.io/jetstack/cert-manager-startupapicheck`
- `quay.io/jetstack/cert-manager-ctl` for cert-manager `v1.14` and earlier; from cert-manager `v1.15` onward, `cmctl` is released from the separate [`cert-manager/cmctl`](https://github.com/cert-manager/cmctl) repository instead.

I think we safely can remove all references to the cert-manager-ctl image in the current docs. This only affects unsupported releases of cert-manager.

You can browse the available tags for each image directly on Quay:

- [`cert-manager-controller` tags](https://quay.io/repository/jetstack/cert-manager-controller?tab=tags)
- [`cert-manager-webhook` tags](https://quay.io/repository/jetstack/cert-manager-webhook?tab=tags)
- [`cert-manager-cainjector` tags](https://quay.io/repository/jetstack/cert-manager-cainjector?tab=tags)
- [`cert-manager-acmesolver` tags](https://quay.io/repository/jetstack/cert-manager-acmesolver?tab=tags)
- [`cert-manager-startupapicheck` tags](https://quay.io/repository/jetstack/cert-manager-startupapicheck?tab=tags)
- [`cert-manager-ctl` tags](https://quay.io/repository/jetstack/cert-manager-ctl?tab=tags)

I don't think we usually update/backport docs to older releases. cert-manager 1.14 is out of support for a long time. Please revert this.
