Error: `uninitialized constant Hashid` when using Rails from `main` branch.

[Paul-Bob]

Failure/Error: include Hashid::Rails

       NameError:
         uninitialized constant Hashid

           include Hashid::Rails
                   ^^^^^^^^
         Did you mean?  Hashids

This only happens when using rails from main branch.

    gem "rails", github: "rails/rails", branch: "main"
    gem "activestorage", github: "rails/rails", branch: "main"
    gem "hashid-rails", "~> 1.4", ">= 1.4.1"
