title: Ionic 5 - How to replace default icon and splash screen image and generate resources
body: <p>I recently started using ionic 6 and capacitor(not cordova), and I don't know how to replace its default application icon and splash screen. 
  Is there any way to do it and generate resources using ionic capacitor cli like what we were doing with cordova(ionic cordova resources android)?
  where should I replace icon and splash images with my own? after adding android platform using capacitor(ionic cap add android), it generates icon and splash images in android resources, but I don't know how to replace my own image.</p>
