socket documentation should mention AF_UNSPEC in the section on constants and getaddrinfo() docs

Documentation

In the socket module documentation

There should be a mention of AF_UNSPEC alongside AF_INET, AF_INET6 and AF_UNIX in the constants section.
Also e.g. in the getaddrinfo() entry, it should be mentioned you can pass socket.AF_UNSPEC instead of 0.
The difference matters if automated testing is checking type annotations (at least I had this issue submitting
a pull request for pythonosc).

The default family argument for getaddrinfo is 0.
This has type int, not type socket.AddressFamily, whereas socket.AF_UNSPEC,
has the type socket.AddressFamily, but corresponds to the integer 0.

This makes a difference when type annotations are being checked
and the argument to family is expected to be of type socket.AddressFamily.

Comece pela documentação do módulo socket, especificamente pela seção de constantes e pela entrada de getaddrinfo(). Mencione AF_UNSPEC juntamente com AF_INET, AF_INET6 e AF_UNIX, e documente que ele pode ser passado no lugar de 0 para o argumento family. Considera-se concluído quando ambas as referências solicitadas explicarem a distinção relevante para o tipo.
