swagger: fix swagger comment for Create DID API

[arnabghose997]

The Create DID handler function doesn't have a correct Swagger comment defined on top of it.

rubixgoplatform/server/did.go

Lines 37 to 38 in e1b6b9a

	// APICreateDID will create new DID
	func (s *Server) APICreateDID(req *ensweb.Request) *ensweb.Result {

For reference, refer Smart Contract generation API

rubixgoplatform/server/smart_contract.go

Lines 89 to 101 in e1b6b9a

	// SmartContract godoc
