Update module dependencies for fabric Go Chaincode

[davidkel]

• fabcar
• fixed-asset
• fixed-asset-base

[davidkel]

For fabcar:

1. delete go.mod and go.sum files
2. update the dependencies in the code
   change

	"github.com/hyperledger/fabric/core/chaincode/shim"
	sc "github.com/hyperledger/fabric/protos/peer"

to

	"github.com/hyperledger/fabric-chaincode-go/shim"
	sc "github.com/hyperledger/fabric-protos-go/peer"

ensure you have go 1.16 or 1.17 installed
3. in fabcar/go directory run go mod init fabric/samples/fabcar/go
4. then run go mod tidy

[davidkel]

for fixed-asset and fixed-asset-base

1. delete go.mod and go.sum files
2. delete the vendor directory
3. run go mod init fabric/api/fixed-asset/go
4. run go mod tidy
5. run go mod vendor

do we include the vendor directory in the commit ?
