feat(scheduler-and-scheduler-targets): graduate to stable 🚀

[gracelu0]

Issue # (if applicable)

Closes #31785 .

Description of changes

We are excited to graduate the @aws-cdk/aws-scheduler-alpha and @aws-cdk/aws-scheduler-targets-alpha modules to STABLE.
They now live on as aws-cdk-lib/aws-scheduler and aws-cdk-lib/aws-scheduler-targets.

The Group construct (deprecated) has now been removed and ScheduleGroup should be used instead.
