I upgrade organizer controllers to 1.7

[reviewpad]

AI-Generated Summary: This pull request includes several enhancements to the organizer controller in the Bokken Web application.

Firstly, the organizer_controller.ex has been upgraded, with changes including the modification of controller usage, changes in rendering view semantics, and changes in response headers. For example, the controller now uses BokkenWeb, :controller instead of BokkenWeb, controller: "1.6". The render function now uses atom instead of string for view rendering. The location header has been manually written instead of using the Routes.organizer_path.

Additionally, a new file organizer_json.ex has been created to handle the data conversion of the organizer.

The organizer_view.ex has been deleted and it seems its functionalities have been moved to the new organizer_json.ex.

Finally, test cases for organizer_json.ex have been added to ensure the correct working of the functions provided by the module. These tests cover rendering a single organizer (show) and a list of organizers (index).

The updates made are aimed at improving the structure and readability of the code, enhance separation of concerns, and provide unit tests to validate the behavior of the organizer JSON handling.

Don't forget to replace this:

To upgrade to 1.7 we need to transform the views files to JSON files and delete the views. So we don't need to change the views files, right ?

Merge with main 🙏🏻

We should wait for #198 to be merged first, because it adds tests for a functionality that is being changed here.
