add bulk pubsub example for js

Resolves: https://github.com/diagridio/issues/issues/2733

As discussed in https://github.com/diagridio/issues/issues/2733#issuecomment-1973571828, we need to add bulk pubsub example code additionally to make it compatible with dapr.

tips: the bulk pubsub would use routes pubsub/bulk-orders and pubsub/bulk-neworders, so make sure you setup catalyst resources correctly before trying it :)

I did manual test, and believe this help to drop unexpected retries and let consumer only receive bulk events exactly once: (feel free to change entryId and event to any string)

curl -X POST http://localhost:5001/pubsub/bulk-orders \
  -H 'Content-Type: application/json' \
  -d '[
        {
            "entryId": "1",
            "event":  "first text message..........1111111111",
            "contentType": "text/plain"
        },
        {
            "entryId": "2",
            "event":  {
                "message": "second JSON message......22222222222"
            },
            "contentType": "application/json"
        }
      ]'

As per discussion the HTTP request sample can be changed flexibly. To make it more align with existing samples, something maybe:

curl -X POST http://localhost:5001/pubsub/bulk-orders \
  -H 'Content-Type: application/json' \
  -d '[
        {
            "entryId": "0",
            "event":  "orderId: 1",
            "contentType": "text/plain"
        },
        {
            "entryId": "1",
            "event":  {
                "message": "orderId: 2"
            },
            "contentType": "application/json"
        }
      ]'

chatted with @kendallroden and she expected the HTTP sample text can align with the existing order sample for pubsub, so I left this comment

guess we can design it more carefully when updating related docs
