[PATCH] Documentation/process: Replace broken link with snapshot

[Clayton Whitelaw]

The link is for the reference article, "The perfect patch":
https://www.ozlabs.org/~akpm/stuff/tpp.txt

This link is down currently and apparently since at least 2022 Jan:
https://web.archive.org/web/20220112192643/https://www.ozlabs.org/~akpm/stuff/tpp.txt

Replace with most recent good snapshot, from 2021 Oct
