Kubectl One-line Installation Support

[lunarwhite]

Hello community.

From the README, it is saying:

Or alternatively, assuming that you have installed cert-manager in the cert-manager namespace, you can use a single kubectl command to install Google CAS Issuer. Visit the GitHub releases, select the latest release and copy the command, e.g.

kubectl apply -f https://github.com/jetstack/google-cas-issuer/releases/download/v0.6.1/google-cas-issuer-v0.6.1.yaml

It's really a straightforward and useful option for users who don't have Helm installed. However, starting from v0.9.0, it appears that the single YAML manifest for One-line Installation is no longer included with the release.

I'm wondering if the kubectl One-line Install method is still supported, or if there's any workaround available.

We currently don't publish a static manifest for one-line installs.
I think helm template could be a very useful middle ground here.
The README.md should be updated to reflect this change (see https://github.com/cert-manager/openshift-routes/blob/main/README.md?plain=1#L73 as example).
