Adding `details` field to `Task` class

[alallema]

The Java class Task which retrieves the response from Meilisearch for a task contains these fields:

    protected String status = "";
    protected int uid = 0;
    protected String indexUid = "";
    protected String type = null;
    protected String duration = "";
    protected Date enqueuedAt = null;
    protected Date startedAt = null;
    protected Date finishedAt = null;
    protected TaskError error = null;

But the actual response send by Meilisearch is like:

{
	"uid": 225,
	"indexUid": "WaitForTaskTimoutInMs",
	"status": "succeeded",
	"type": "documentAddition",
	"details": {
		"receivedDocuments": 30,
		"indexedDocuments": 30
	},
	"duration": "PT0.031713875S",
	"enqueuedAt": "2022-01-26T16:54:46.993341418Z",
	"startedAt": "2022-01-26T16:54:46.995596001Z",
	"finishedAt": "2022-01-26T16:54:47.027309876Z"
},

It should be more accurate to add a details field to the Task class to be able to have the entire answer from the Meilisearch API.

Hi @kuruvasatya,
We have chosen not to assign people to our issues anymore because sometimes people ask to be assigned and never come back, which discourages real volunteer contributors from opening a PR to fix this problem.
But I see you already propose an issue, I will review it 😊
Thanks for contributing to Meilisearch ❤️
