Move to Alpine 3.20 and a newer version of s6-overlay

Description

3.20 is out and the s6 overlay you are using is a version from 2021.

Do you have any issue with current s6 overlay v2? I didn't make the jump to s6 v3 yet as it needs a huge refactor but I added support for Alpine 3.20 in https://github.com/crazy-max/docker-alpine-s6/releases/tag/2.2.0.3-r24

Also please create an issue per request, it eases triage in the repo.

No, no issues with s6 just stood out that it's an older version. Thanks!

There is no real benefit going up to Alpine 3.20 other than reduced build times with Python 3.12. The next major milestone for this docker container should be to wait for GCC 14.2 to be released and Alpine Linux to incorporate it.
