ReadMe: myAPI variable in the example section is confusing #280

Description

@kenozordi

In the example section of the README, the following code snippet uses a variable named myAPI:

SwaggerParser.validate(myAPI, (err, api) => {
  if (err) {
    console.error(err);
  } else {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  }
});

It’s not immediately clear what myAPI means or how it should be defined before this call.
For someone new to this tool, this could be confusing. It might refer to a file path, an object, or a URL.

It might be clearer to replace myAPI with something more descriptive like

// Path or URL to your Swagger/OpenAPI definition
const myAPI = "path/to/api.yaml";
SwaggerParser.validate(myAPI , (err, api) => {
  if (err) {
    console.error(err);
  } else {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  }
});

This small clarification would make the example easier to follow for new users and reduce confusion about how to use the validate() method correctly.
