Return the correct file path from `wp_crop_image()` when a developer modifies the file type with via the `image_editor_output_format` filter. Previously the function would return a broken file reference containing the original file extension rather than the one specified via the filter. Props mat-lipe, adamsilverstein. Fixes #55403. git-svn-id: https://develop.svn.wordpress.org/trunk@53292 602fd350-edb4-49c9-b593-d223f7449a82
