ruby-3.3: System gems extensions are not build

[Schmitze333]

When installing the ruby-3.3 or ruby-3.3-dev package, the native extensions of the system gems seem to not have been built.

This results in warnings like:

Source locally installed gems is ignoring #<Bundler::StubSpecification name=debug version=1.9.1 platform=ruby> because it is missing extensions

Minimal steps to reproduce:

docker run --rm -it cgr.dev/chainguard/wolfi-base

# In the container...
apk update && apk add ruby
gem install bundler

Manual workaround

apk add build-base
gem pristine --all
apk del build-base
