	spec.add_runtime_dependency "openssl"

The openssl gem is a development dependency. It is not a runtime dependency. This is only needed because of a GitHub Action Runner configuration issue where their macOS images are not up to date with SSL certificates.

Users do not need the openssl gem at all.

Solution: move it to Gemfile
