Mojaloop chart does not support ingress 0.22.* or later

[mdebarros]

Mojaloop chart does not support ingress 0.22.* or later due to the rewrite rules no longer being backwards compatible.

Refer to the following -> https://kubernetes.github.io/ingress-nginx/examples/rewrite/#rewrite-target

Specifically the annotations on the values.yaml files need to be changed from nginx.ingress.kubernetes.io/rewrite-target: '/' to nginx.ingress.kubernetes.io/rewrite-target: '/$1'.

All values files will need to be updated to reflect this change.
