Feat (SRM) add failed events slack notification

[raylrui]

solve: #875

Subscribe to the 'SequenceRunStateChange' event, and send the slack notification topic when the failed event is triggered.
event rules as:

eventRule.addEventPattern({
      source: ['orcabus.sequencerunmanager'],
      detailType: ['SequenceRunStateChange'],
      detail: {
        status: ['FAILED'],
        id: [{ exists: true }],
        instrumentRunId: [{ exists: true }],
        sampleSheetName: [{ exists: true }],
        startTime: [{ exists: true }],
      },
    });

It will generate Failed SRM events message to slack channel( biobots for prod account).
Example message format:

PS:
(SNS topic issue) Because we set up 'alerts' sns topic manually, CDK can't modify the resource policy as it is an "imported" resource in our stacks. So we need to add a resource policy to allow EventBridge to publish to this SNS topic.
example of manually added resource policy:

{
      "Sid": "AWSEvents_OrcaBusBeta-SequenceRunManagerStackSlackNotificationRule_Id85755e27-3dd5-408e-9091-9cbc7315db7e",
      "Effect": "Allow",
      "Principal": {
        "Service": "events.amazonaws.com"
      },
      "Action": "sns:Publish",
      "Resource": "arn:aws:sns:ap-southeast-2:843407916570:AwsChatBotTopic-alerts"
      }
