fix(wait): Removes ingress checks

v3 port of #6792

After doing some more digging, I found out that updating the status
of an `Ingress` object is completely optional. Because of this, Helm
cannot support ingresses with the `--wait` flag because there is no
standard way to identify that they are ready
