✨ Feature Request

Hi, i was hoping to be able to use Magic in a new Rails 7 app with Ruby 3, however it appears the dependencies of this gem require Ruby (~> 2.2) and so i get an error when running bundle install.

🧩 Context

Here's my Gemfile

gem "magic-admin", ">= 0.1.2"

Output after running bin/bundle install

Bundler found conflicting requirements for the Ruby version:
  In Gemfile:
    Ruby (~> 3.0.2.0)

    magic-admin (>= 0.1.2) was resolved to 0.1.2, which depends on
      eth (~> 0.4) was resolved to 0.4.0, which depends on
        ethereum-base (~> 0.1.4) was resolved to 0.1.4, which depends on
          digest-sha3 (~> 1.1) was resolved to 1.1.0, which depends on
            Ruby (~> 2.2)
