Correct documentation in JsonApiClient class

[pueffl]

Please correct the following code from your documentation:

final httpClient = Client();
final jsonApiClient = JsonApiClient(httpClient);
final url = Uri.parse('http://localhost:8080/companies/2');
final response = await jsonApiClient.fetchCollection(url);
httpClient.close(); // Don't forget to close the http client
...

When you just copy the code in a test to get some experience how the library works, you get the following two problems:

• the construction of Client() doesn't work (anymore)
• it is also not possible to call httpClient.close()

There was an incorrect URL used in the documentation. The issue has been fixed in 3.2.1. Please try again. If it still fails, please post here the entire dart file you're using and the error logs.
