BUG: Incorrect type definition for PanelManager.addPanel

@artf - You didn't read the full sentence. You can clearly see in the code itself, it requires the argument given as the full Panel object. In your docs (as linked), you are not giving it the full Panel object in the example, but rather just an object with those projects. Your example is the following:

editor.Panels.addPanel({
  id: 'panel-top',
  el: '.panel__top',
});

Which TypeScript will complain about because the object given to it isn't an instance of a Panel nor is it an array of the object's properties.

The documentation on the site says the parameters given can be only an object with the properties

Sorry, where exactly do you read that statement?
