RI-7484 Rework the visuals of the success notification when sample data is imported

[valkirilov]

Description

Update the visuals of the toast notification when the sample data import finishes successfully, and make it look less broken:

• rework the interface for the success notifications to allow us to customize the visibility of the action buttons and the default dismiss button
• update the notification itself, to use Redis UI styles only, and make it look not broken

Before	After

How it was tested

1. Open Redis Insight and connect to the existing database (or establish a connection to a new instance)
2. Go to the Browser page and make sure the database is empty, so you can see the "Load sample data" button
3. Confirm the import and wait for the notification to appear

PS: You can use the flushdb command in the CLI to wipe all data from the Redis instance, if it's not empty

Other use cases

The same notification can be used by a Workbench tutorial that I wasn't able to find how to trigger via action in the app, but I have fixed the visual of the notification, and you can manually trigger it via the following action:

const data: IBulkActionOverview = {
      id: 'empty',
      databaseId: '867c2756-d291-4e03-b19e-f95d6ca89248',
      type: BulkActionType.Upload,
      summary: {
        processed: 234,
        succeed: 234,
        failed: 0,
        errors: [],
        keys: [],
      },
      status: BulkActionsStatus.Completed,
      duration: 34,

      // Not relevant for this notification, but required in the interface
      progress: {
        total: 0,
        scanned: 0,
      },
      filter: { type: RedisDataType.Hash, match: '*' },
}

dispatch(addMessageNotification(successMessages.UPLOAD_DATA_BULK(data)))
