This condition is prioritizing `addr` over `dest`

https://github.com/knative/pkg/blob/559de7ee8c6788ec4561b170181556f6fa0a36af/resolver/addressable_resolver.go#L257-L259

we should set `addr.CACerts` to whatever `dest.CACerts` has set if `dest.CACerts` is set/non empty regardless of the value of `addr.CACerts`

## Additional Info

- The fix should be backported to `release-1.11` branch
