Onboard kubernetes-cert-manager to ci-mgmt (#892)

[kubernetes-cert-manager](https://github.com/pulumi/pulumi-kubernetes-cert-manager)
is an older provider whose releases are currently
[broken](https://github.com/pulumi/pulumi-kubernetes-cert-manager/actions/runs/7996599325).

Rather than hacking together a one-time fix to unblock releases, it
would be better to manage this repo via ci-mgmt so it can stay
up-to-date with the rest of the ecosystem.

This can merge after
pulumi/pulumi-kubernetes-cert-manager#38, which
updates the repo to work with these workflows.
