when using rules to delete packages, remove unclean bugs (#34632)

By default, the code extracts 200 package versions. If too many packages
are generated every day or if rule cleaning is enabled later, which
means there are more than 200 versions corresponding to the library
package, it may not be cleaned up completely, resulting in residue

Fix #31961
