[3.13] ast docs: Fix description of ast.Constant (GH-134741) (#134912)

Contrary to the current docs, ast.Constant will never hold containers
such as frozenset or tuple; the Python parser only emits it for simple
literals.

For precision, add the exact list of types that may be contained in an
ast.Constant.
