A minimum example to trigger the error described in rubygems/rubygems#5422.
The Gemfile.lock was built with force_ruby_platform set to true.
I noticed the problem locally when trying to install sorbet (resp sorbet-static)
in a Docker container on an Apple M1 mac:

executor failed running [/bin/sh -c bundle install]: exit code: 1
It turned out, there simply is no gem version of sorbet-static for aarch64-linux
which caused bundler to crash itself.
If anyone should make it here with the same problem through Google:
As my Docker images are mainly used in CI (which is amd64), I simply
disabled installing sorbet in containers on M1 macs completely.
# Gemfile
install_if -> { RUBY_PLATFORM != "aarch64-linux" } do
