Not compatible with Ruby 3.1.2

[Leo22Prieto]

When I had the gem in my Gemfile there is an error :

Bundler found conflicting requirements for the Ruby version:
In Gemfile:
solidus_static_content was resolved to 2.0.0, which depends on
Ruby (~> 2.5)

Current Ruby version:
Ruby (= 3.1.2)

Bundler could not find compatible versions for gem "solidus_backend":
In Gemfile:
solidus_backend (~> 3.3)
solidus_static_content was resolved to 1.0.0, which depends on
solidus (< 3, >= 1.1) was resolved to 1.2.0.beta1, which depends on
solidus_backend (= 1.2.0.beta1)
