Copied from #7991:

If you look at https://certbot.eff.org/docs/api/certbot.compat.filesystem.html, you'll notice many formatting errors which should be fixed.

That's the bare minimum which I think should be done, but I think we should also see what we can do to avoid these problems from happening in the future. Is there a way we could build the docs in CI and check for these problems?

Feature request

Feature description

We have global options to enable Dockerfile and docker-compose.yaml -- we should provide correct syntax highlighting for these files when present.

We should make the syntax highlighting for these async so that the Prism data is generated in a separate bundle file and is present in the main bundle, being loaded only when needed.

How the fea

Is your feature request related to a problem? Please describe.
At cert-manager 1.0, there is ServiceMonitor to scrape certs metrics, but there is no alert(s) on certs renew failures to cluster operator.

Describe the solution you'd like
PrometheusRule object with alerting rules about expiring certs. Plus, ability to extend/override default rules via helm values.
