Add support for go version 1.18+

[hmoazzem]

It might be expected because of https://github.com/hyperledger/fabric-sdk-go/blob/main/test/fixtures/config/overrides/local_entity_matchers.yaml, but I haven't figured that out yet. Faced with the same issue #265, I resolved by downgrading golang to version 1.18. Reproducible scenario that works in go v1.18, but not higher.

config.yaml

version: 1.0.0

client:
  tlsEnable: true

  channel0:
    orderers:
    - orderer1.orderer

	client, err := channel.New(clientChannelContext)
	if err != nil {

	}

	response, err := client.Execute(channel.Request{ChaincodeID: chaincodeID, Fcn: "YourFunction"})
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(string(response.Payload))
}

Same issue #260

I've replaced fabric-sdk-go in vendor directory with git clone https://github.com/hyperledger/fabric-sdk-go, and issue was solved.
