/**
 * Returns a (CKEditor 5) package name the file belongs to.
 *
 * E.g., for the path to the file:
 *
 *        "/foo/ckeditor5/packages/ckeditor5-bar/baz.css"
 *
 * it outputs
 *
 *        "ckeditor5-bar"
 *
 * It always returns the last found package. Sometimes the whole project can be located
 * under path which starts with `ckeditor5-`. In this case it isn't a package and it doesn't make
 * sense to return the directory name. See #381.
 *
 * E.g., for the path from the package directory to the file:
 *
 *        "/foo/ckeditor5/packages/ckeditor5-editor-classic/node_modules/@ckeditor/ckeditor5-bar/baz.css"
 *
 * it outputs
 *
 *        "ckeditor5-bar"
