Ability to update tags on AWS::Batch::SchedulingPolicy

### Name of the resource

Other

### Resource name

AWS::Batch::SchedulingPolicy

### Description

It is currently not possible to update the tags on the CloudFormation stack if it contains an AWS::Batch::SchedulingPolicy. This should work as it does for most other resources so that stack tags can be updated when a template contains one, without needing to recreate.

Our use case: As we have tag policies in our organisation, we sometimes need to add new tags or modify tags on existing stacks. All of our stacks with AWS::Batch::SchedulingPolicy in them fail when we do this and as we deploy to multiple accounts and multiple regions, we rely on CloudFormation doing the update.

### Other Details

_No response_

Start with the AWS::Batch::SchedulingPolicy resource and reproduce a CloudFormation stack-tag update on a stack containing it. Compare its behavior with resources that already support tag updates, including whether the update happens in place across accounts and regions. Done means stack tags can be added or changed without recreating the scheduling policy.
