Circular dependency between `mapping` term `collections.abc.Mapping`

Documentation

The mapping (1) glossary term is defined as

A container object that supports arbitrary key lookups and implements the methods specified in the collections.abc.Mapping or collections.abc.MutableMapping abstract base classes. Examples include dict, collections.defaultdict, and collections.Counter.

Whereas for example collections.abc.Mapping(2) and collections.abc.MutableMapping(2) have the documentation:

ABCs for read-only and mutable mappings.

I expected either the documentation on a mapping or the documentation on the ABC's to describe or link to what methods a (mutable) mapping implements. Now they refer to each other in a circle for the actual specification of what methods are required.

Prüfe zuerst den verknüpften PR gh-149348, untersuche anschließend den Glossareintrag zu Mapping sowie die im Bericht verlinkte Dokumentation zu collections.abc.Mapping und collections.abc.MutableMapping. Aktualisiere die Dokumentation so, dass die erforderlichen Mapping-Methoden beschrieben werden, ohne dass die beiden Einträge zirkulär aufeinander verweisen.
