[Nanashi-lab]

closes #1559

completely fixes the issue in #1559

cause -
golem-worker-service/src/grpcapi/api_definition

            create_api_definition_request::ApiDefinition::Openapi(definition) => {
                let converted = OpenApiHttpApiDefinition(
                    serde_json::from_str(&definition).map_err(|_| bad_request("Invalid JSON"))?,
                );

fix -
Now accepts both JSON and YAML, added two more tests (works in both http-mode and grpc)
deps.done file is created while doing cargo make fix (This wasnt the case, a week+ ago)

Fixed the whole ticket

Grpc failed because it could only accept APIDefinition::OpenAPI in Json format, now it can accept both Json and Yaml

It checks for Yaml, on failure checks for Json -> and passes the value to create the api definition

There are now two more tests in integration-tests/api/api_definition.rs
create_openapi_yaml_definition and create_openapi_json_definition

Now creating api definition integration test is possible through both http and grpc mode. Please Review and Accept, thank you.
