[FEAT] Allow StrapiV4 CRUDFilters to do deep filter

Is your feature request related to a problem? Please describe. On Strapi, you can use objects to make deep filters (https://docs.strapi.io/developer-docs/latest/developer-resources/database-apis-reference/rest/filtering-locale-publication.html#deep-filtering) Example:

filters: {
    chef: {
      restaurants: {
        stars: {
          $eq: 5,
        },
      },
    },
},

GET /api/restaurants?filters[chef][restaurants][stars][$eq]=5

Refine, only allows arrays, with logical filters or conditional filters (https://refine.dev/docs/guides-and-concepts/data-provider/handling-filters/): Example:

const filter = [
    {
        field: "name",
        operator: "eq",
        value: "John",
    },

If I try to use a relation field as a filter, strapi will throw an error.

Describe the solution you’d like I´d like to use deep filters so I can filter some relational tables. On my real case, I´m doing a todo list for each project. I also need to filter this todo list based on its procedure, on another component, and I need to mutate it too. Doing this filtering makes easier on the code logic.

Describe alternatives you’ve considered I can cheat the URL constructor doing this:

const filter = [
    {
        field: "chef[restaurants][stars",
        operator: "eq",
        value: "John",
    },

It converts to this: /api/restaurants?filters[chef][restaurants][stars][$eq]=5 It works!

Hello, can we do something like:

{
    field: "chef.restaurants.stars",
    operator: "eq",
    value: 5,
}

And its must works only in Sptrapi provider. This solution not implements “dirty” logic in core.

p.s. Dot separated like in Laravel.
