This covers the question "how", but not "what".
So my two cents:
"Backported" is probably the wrong wish.
https://backports.debian.org/Contribute/
says:
"Backports are about additional features that are only offered in a
new version, not a replacement for getting fixes into stable - use
stable-updates for that."
That would probably mean to patch the existing pigz package in Debian 12
by the upstream remedy
"Make pigz compatible with two-component zlib version numbers. "

The new state can already be seen in
https://sources.debian.org/src/pigz/2.8-1/pigz.c/#L1339
The old state is in
https://sources.debian.org/src/pigz/2.6-1/pigz.c/#L1317
But there the "// -- check ..." comment is missing in favor of a line
#ifndef NOTHREAD
So a patch proposal would need some minor hand work.
There remains the question, though, why you run into zlib-1.3 on a
Debian "stable" system where the zlib version is "1:1.2.13.dfsg-1":

Have a nice day :)
