What happened?

When attempting to add a transit gateway using to a ResourceAssociation the following error occurs:

cannot resolve references: mg.Spec.ForProvider.ResourceArn: cannot get referenced resource: Subnet.ec2.aws.upbound.io "[transitgateway-name]" not found

How can we reproduce it?

1. Create a TransitGateway
2. Create a ResourceShare
3. Create a ResourceAssociation using resourceArnRef: with the name of the TransitGateway

apiVersion: ram.aws.upbound.io/v1beta1
kind: ResourceAssociation
metadata:
name: name-ra
spec:
forProvider:
region: [region]
resourceArnRef:
name: [transitgateway-name]
resourceShareArnRef:
name: [resourceshare-name]
providerConfigRef:
name: [provider-config]
