(aws-scheduler-targets-alpha): Add SnsPublish Target

[filletofish]

Describe the feature

Work to support L2 constructs for AWS Scheduler is in progress (#23394). See the approved RFC. RFC planned to add 12 templates targets, but only Lambda Invoke is currently implemented (#26575).

This issue tracks implementation of SnsPublish target to publish a message to a SNS topic.

Use Case

Customers would like to use templated target SnsPublish to be able to publish a message to a SNS topic. on schedule. L2 target construct should grant required permissions to the AWS Scheduler to publish a message to a SNS topic.

Proposed Solution

The proposed solution needs to be adopted to the recent examples of LambdaInvoke (https://github.com/aws/aws-cdk/blob/main/packages/%40aws-cdk/aws-scheduler-targets-alpha/lib/lambda-invoke.ts).

Solution should also include unit and integration tests.

export class SnsPublish extends ScheduleTargetBase {
    constructor(
      private readonly topic: sns.ITopic,
      private readonly props: ScheduleTargetBaseProps,
    ) {
      super(props, topic.topicArn);
    }

    protected addTargetActionToRole(role: iam.IRole): void {
     // TODO: Check if target and schedule are in the same account and region
     // TODO: Check if target and role are in the same account

      this.topic.grantPublish(role);      
    }
  }
