Describe the feature

In CfnBackupPlan, you can now specify rules with the indexActions prop. This is currently not possible on the BackupPlanRule class.

https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_backup.CfnBackupPlan.BackupRuleResourceTypeProperty.html#indexactions

Use Case

So users can enable Backup indexes for specific resource types within a rule.

Proposed Solution

indexActions just needs to be added to BackupPlanRuleProps and sent through within the rule.ts class. I have a solution working locally.
