Bump cert-manager to v1.5.4 #244
Description
The current version we are using (1.4.0) references an old version of the Ingress resource, resulting in annoying warnings, and we have seen a couple instances of an issue where cert-manager stops trying to renew certs until the pod is killed, which is not good. This may have been fixed in 1.5.0, but let's go to the newest version.
Let's make sure to test this in a real cluster too.
