[State] Add missing Go examples

[hhunter-ms]

Description

Add examples for Bulk State and StateStore transactions for Go

Issue reference

PR will close: #4059

[salaboy]

ok, I've checked the code and made a few suggestions.

This will not work, as this is an array of BulkStateItems, what's the objective of this println? show all the Items in the array? We might need to loop here.

@salaboy I'm least familiar with Go, so I'm not sure about the printIn haha I may have grabbed it when piecing together examples

@salaboy
Yes, @hhunter-ms is asking the the equivalent of this below, but for bulkstate, which means iterating over each item and showing it's value. This is just for a simple example to show how the API works

		result, err := client.GetState(ctx, STATE_STORE_NAME, "order_1", nil)
		if err != nil {
			panic(err)
		}
		log.Println("Result after get:", string(result.Value))

Ok, then @hhunter-ms something like this would work

                 items, err := client.GetBulkState(ctx, STATE_STORE_NAME, keys, nil, 100)
		if err != nil {
			panic(err)
		}
		for _, item := range items {
			log.Println("Item from GetBulkState:", string(item.Value))
		}
