Bump since it was released https://www.debian.org/News/2023/20230610

I have rebased the branch to fix conflicts. At the moment it does not compile with apline17 and 18 due to openssl version iirc, but not remember for sure. update.sh breaks versions.json for 2.7, I am not sure if I need to fix this script and what it does at all.

I believe the single change should be

diff --git a/versions.sh b/versions.sh
index 0901026..6848b79 100755
--- a/versions.sh
+++ b/versions.sh

                                (

and everything else should be autogenerated by ./update.sh (don't see any special cases for buster, so nothing else to remove + dunno why need_openssl flag is needed).

(NB: I'm not a maintainer)

Ah, missed + 2.7.8 support part. Also shouldn't be here, it's EOLed/unsupported and was dropped because of that.

[yosifkit]

Force pushed to drop out Ruby 2.7 and buster; also added same fix as https://github.com/docker-library/python/pull/822#discussion_r1227154811.

Edit: kept buster for Ruby 3.0 since it doesn't support OpenSSL 3.

Thank you for accepting this PR! You would be surprised how many people still sit on 2.7.x.
