`ruby:3.2`: No network connection established

Starting a simple Ruby3.2 HTTP server (PR #23) doesn't provide a running network connection connection. Use the following commands to replicate:

wget https://raw.githubusercontent.com/unikraft/catalog-for-maintainers/main/utils/start-buildkit.sh
source start-buildkit.sh
git clone https://github.com/unikraft/catalog
cd catalog
git remote add unikraft-upb https://github.com/unikraft-upb/catalog
git fetch unikraft-upb
git checkout -b razvand/library/ruby unikraft-upb/razvand/library/ruby
cd library/ruby/3.2
sed -i "s/# CONFIG_LIBSYSCALL_SHIM_STRACE: 'y'/CONFIG_LIBSYSCALL_SHIM_STRACE: 'y'/" Kraftfile
kraft build --no-cache --no-update --plat qemu --arch x86_64
kraft rm --all ; kraft run --rm --log-type basic --log-level debug -M 256M -p 8080:8080 .
