Update ca-certs base image (#4153)

* Use a newer debian image for certs

stable-20211201 is based on the current `oldstable` release, `bullseye`,
and has an older ca-certificates package (20210119), whereas 20240110 is
based on the current `stable` release, `bookworm`, and has a more up to
date ca-certificates package (20230311)

* Clean up unneeded removal

Current versions of the ca-certificates package no longer include
CNNIC_ROOT certificates, so the separate trimming step is no longer necessary
