By setting recovery_point_tags with the module tags we loose the name of the resource on the snapshots

### Describe the Bug

Tags set in recovery_point_tags will override the backup resource original tags, including the name.
As it is all the snapshots will have the name assigned to the module (via context or vars).

### Expected Behavior

Keep the resource name in the snapshots created by AWS Backup

### Steps to Reproduce

Use the module and set the name using var.name or var.context.

### Screenshots

_No response_

### Environment

_No response_

### Additional Context

_No response_

Start by inspecting the module's recovery_point_tags handling and reproduce the behavior with the name set through var.name or var.context. Done means AWS Backup snapshots retain the original backup resource name instead of replacing it with the module name.
