docs: bump version to v0.73.1

Refs #4288, #4284. Ports the latest tooling commit
to the guide. Updates the installer logic to make use of the new

copy/pasteable in the guide (#4255) and use .tar.gz for archive format
(#4256). I opted to leave the pd instructions largely as they are.

 As of v0.64.1 (released 2023-12-12), we build Linux binaries on Ubuntu 22.04. If these binaries don't work for you out of the box,
 you'll need to [build from source](../../dev/build.md), or use the container images.
