Arvados

This is necessary to support Ubuntu 22.04+, Debian 12+, and RHEL 9+: those distributions have OpenSSL 3.0, which is only supported by Ruby 3.x, which is only supported by Rails 6.

This ticket includes transient dependencies like our google-api-client fork:

Bundler could not find compatible versions for gem "activesupport":
  In Gemfile:

      arvados-google-api-client (>= 0.7, < 0.8.9) was resolved to 0.8.7.4, which depends on
        activesupport (>= 3.2, < 5.3)

    rails (~> 6.0.0) was resolved to 6.0.1.rc1, which depends on
      activesupport (= 6.0.1.rc1)
