Build fails because of unknown wget option `show-progress`

[thass0]

Describe the bug

Building with kraftkit fails because GNU Wget2 2.1.0 doesn't accept the flag show-progress. It looks like this flag is only available for GNU wget 1. Based on the man page, the --force-progress flag for GNU Wget2 has a similar effect to the --show-progress flag. The change from --show-progress to --force-progress is mentioned on the Wget2 gitlab page:

Steps to reproduce

git clone https://github.com/unikraft/catalog
cd catalog/library/nginx/1.25/
# Based on https://unikraft.org/guides/catalog-behind-the-scenes#nginx
docker run -d --name buildkitd --privileged moby/buildkit:latest
export KRAFTKIT_BUILDKIT_HOST=docker-container://buildkitd
kraft build --plat qemu --arch x86_64

Expected behavior

The right flat for Wget should be chosen based on the version of Wget.
