• added logic to handed operation path within jsonb filters

As per the docs shown here: https://github.com/hasura/ra-data-hasura/tree/master?tab=readme-ov-file#jsonb-filtering

This PR fixes an issue with the filter reducer for JSONB that wasn't parsing or using the operation path. Now the example:

<TextField label="Theme Color" source="users#preferences@_contains@ux#theme" />```

Should produce the correct result:

```json
{
  "where": {
    "_and": [
      {
        "users": {
          "preferences": {
            "_contains": {
              "ux": {
                "theme": "%TEXT"
              }
            }
          }
        }
      }
    ]
  },
  "limit": 10,
  "offset": 0,
  "order_by": {
    "id": "asc"
  }
}

Ideally I would've broken it out to make it testable, but because it uses the introspection results I decided to just make minimal changes to the code and confirm it's functioning on my own project.

@praveenweb is anyone maintaining this library anymore? Who would be able to approve this?
