[issue36490] Modernize function signature format in Archiving section of shutil doc

Inada Naoki added the comment: I don' think they are modern-style vs legacy-style. When explicit default value is present, the default value is documented in signature like `param=42`. On the other hand, when default value is not explicit (just an placeholder), the parameter is expressed
