RDS issue

[tnh]

need a minor change for RDS:

2023-10-25 15:16:56 UTC+1000	DatabaseCluster	CREATE_FAILED	Resource handler returned message: "Cannot find version 5.7.mysql_aurora.2.10.1 for aurora-mysql (Service: Rds, Status Code: 400, Request ID: c5356dd6-cdfd-488a-81f2-e18049469773)" (RequestToken: 8a2a2636-49ed-3918-edc7-c0126f52150d, HandlerErrorCode: InvalidRequest)

I was seeing the same issue and fixed it by changing the RDS cluster and database resources from "Engine: aurora" to "Engine: aurora-mysql" in the aws-refarch-wordpress-03-rds.yaml file.
