Bug: $format in ResourceController is ignored

[rmilecki]

Describe the bug
CodeIgniter\RESTful\ResourceController allows (according to the documentation and source code) specifying output format by setting protected $format to xml or json. There is even ResourceController::setFormat helper.

It doesn't work however as $format seems to be ignored.

In practice calling ResponseTrait::respond results in calling ResponseTrait::format which negotiates output format:

$format = $this->request->negotiate('media', $config->supportedResponseFormats, false);

E.g. I get XML when opening page in web browser and JSON when using CLI curl.

CodeIgniter 4 version
4.0.2

Affected module(s)
ResourceController and ResponseTrait::format.

Expected behavior, and steps to reproduce if appropriate

1. Setting protected $format = 'xml'; should always generate XML response
2. Setting protected $format = 'json'; should always generate JSON response
