Description

This is a follow up task to ARROW-15694 and ARROW-15988.

We need to update the actual content of the Apache Arrow website to no longer refer to the "master" branch. This includes updating links, text snippets, and the README.md for arrow-site. There may also be other files that need to be updated, as well.
