[Proposal] Raise or warn when rails g scaffold detects a reserved ruby word

TLDR; I think it would be a nice addition if rails can warn or raise when user attempts to do “rails generate scaffold” and a reserved word like class is used.

Rails allows this:

bin/rails generate scaffold post title:string class:string

but later on when we try to Post.new we get

irb(main):001:0> Post.new
/Users/administrator/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/bundler/gems/rails-89fc4bf9196f/activerecord/lib/active_record/inheritance.rb:345:in `ensure_proper_type': undefined method `finder_needs_type_condition?' for nil:NilClass (NoMethodError)                                                      
                                                                
        if klass.finder_needs_type_condition?                   
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
