APT Ruby package does not provide /usr/bin/bundle

Hello, Under Debian11 and Ubuntu20.04, the kitchen test command fails on this file because apt-get install ruby installs ruby2.7 which provides /usr/bin/bundle2.7 and $(which bundle) returns nothing.

I fixed this problem by replacing ruby with ruby-bundler which provides the expected executable /usr/bin/bundle

$ apt-file search /usr/bin/bundle
ruby-bundler: /usr/bin/bundle
ruby-bundler: /usr/bin/bundler
ruby2.7: /usr/bin/bundle2.7
ruby2.7: /usr/bin/bundler2.7
