(hotswap): CLI --hotswap fails with RDS Databases in the stack

### Describe the bug

`cdk deploy --hotswap` is not working when an RDS Database is part of the stack.

Following message occurs in the output:
`Could not perform a hotswap deployment, because the CloudFormation template could not be resolved: We don't support attributes of the 'AWS::RDS::DBInstance' resource.`

Note: there are no changes to the database inside of the cdk code used. Only the container image was changed.

### Regression Issue

- [ ] Select this option if this issue appears to be a regression.

### Last Known Working CDK Library Version

_No response_

### Expected Behavior

Container running with new image after the `--hotswap` deployment.
RDS Database should be ignored and not touched

### Current Behavior

Image was build and uploaded.
`cdk deploy --hotswap` finishes with errors.
Old container images are still running (no new deployments)

### Reproduction Steps

1. Create a stack with ECS Fargate container and a RDS Database inside.
2. Change something in the Dockerfile for the container
3. Run `cdk deploy --hotswap`
