need newer ruby for puppet 8 gems

[rwaffen]

to build a container with puppet gem 8.x.y we need ruby 3.2.x but our current ubuntu image has only 3.0.x. we need to get packages from somewhere or another base image. maybe we can switch to ruby-3.3.0. this one is base on debian12.

6.316 Resolving dependencies...
6.434 Could not find compatible versions
6.434 
6.434 Because puppet >= 8.0.1 depends on Ruby >= 3.1.0
6.434   and Gemfile depends on puppet = 8.5.1,
6.434   Ruby >= 3.1.0 is required.
6.434 So, because current Ruby version is = 3.0.2,
6.434   version solving has failed.
