fix: add patch for aws_rds_cluster storage_type replacement bug

[pierskarsenbarg]

Summary

• Ports fix: aws_rds_cluster storage_type change no longer forces replacement hashicorp/terraform-provider-aws#48545 as a new local patch (patches/0028-...patch)
• Removes an incorrect customdiff.ForceNewIf guard on storage_type for non-Aurora RDS clusters that forced resource replacement even though the AWS ModifyDBCluster API supports in-place changes
• No Pulumi SDK/schema changes needed: storage_type has no static ForceNew in the TF schema, so the bridge never derived a replaceOnChanges from this behavior

Test plan

• ./scripts/upstream.sh check_in applied all 28 patches cleanly with no conflicts
• go build ./internal/service/rds/... succeeds against the patched upstream checkout

Fixes: #6554

I linked the wrong issue in the PR text - this has been fixed now

Thanks for working on this! Before merging we just need to add some tests.

1. Run the upstream acceptance test in our CI. Add the TestAccRdsCluster_storageTypeUpdateNonAurora to the aws-upstream-tests.yml

          matrix:
            service:
              - sqs
              - ec2
   +          - rds
              - docdb
              - redshiftserverless
              - cognitoidp
            include:
              - service: sqs
                tests: TestAccSQSQueue
              - service: ec2
                tests: TestAccEC2KeyPair_publicKey
   +          - service: rds
   +            tests: TestAccRDSCluster_storageTypeUpdateNonAurora
              - service: docdb
                tests: TestAccDocDBCluster_basic

2. Similar to the upstream test, we need a Pulumi-side examples test.
