Drop Ruby 2.6 support and update dependencies

Removed Ruby 2.6 jobs from CI workflow to focus testing on newer
supported Ruby versions. Updated Gemfile and documentation to reflect
dropping 2.6 support and upgrading minimum Ruby version to 2.7.8. This
helps ensure the codebase remains secure and compatible with modern Ruby
environments while removing maintenance burden of older versions no
longer receiving security updates.
