freesh-archive-keyring_1.1 breaks apt update in Debian 12

[retrovirus-007 at juno.com]

Hello Linux-libre kernel team,

I was trying to upgrade freesh-archive-keyring_1.2_all.deb, but ran to error message.

dpkg-deb: error: archive '/var/cache/apt/archives/freesh-archive-keyring_1.2_all.deb' uses unknown compression for member 'control.tar.zst', giving up

Same results goes for a local .deb file download/installation from directory path.

Had to install zstd, which isn't automated for the dpkg installer yet. Guess that certain GNU/Linux OS repositories might need catching up to do. Do you know which OS have the recently updated dpkg/installer with zstd packaging capabilities?
Below links show the instructions to repackage incompatible archive package files.
Maybe we should let others know about this change?
