Bundler found conflicting requirements for the Ruby version:
  In Gemfile:
    Ruby x86_64-darwin-20

    bundler (>= 2.1.4, < 3.0) x86_64-darwin-20 was resolved to 2.2.3, which depends on
      Ruby (>= 2.3.0) x86_64-darwin-20

    deploygate x86_64-darwin-20 was resolved to 0.8.3, which depends on
      fastlane (~> 2.148.1) was resolved to 2.148.1, which depends on
        Ruby (>= 2.4)

    deploygate x86_64-darwin-20 was resolved to 0.8.3, which depends on
      fastlane (~> 2.148.1) was resolved to 2.148.1, which depends on
        google-api-client (< 0.39.0, >= 0.37.0) was resolved to 0.38.0, which depends on
          Ruby (~> 2.4)

The workaround is to use ruby-2.x.

dg command depends on fastlane. We wait for fastlane ruby 3.0.0 support to be completed. https://github.com/fastlane/fastlane/issues/17931
