ActiveRecord.column_names should not be mutable

#5857

I have an active record class named Bee. In the rails console

>> Bee.column_names
=> ["id", "created_at", "updated_at"]
>> Bee.column_names.delete 'id'
=> "id"
>> Bee.column_names
=> ["created_at", "updated_at"]

Bee.column_names should be immutable. I suggest the column_names implementation should read as follows instead

       # File activerecord/lib/active_record/base.rb, line 691
691:       def column_names
692:         @column_names = columns.map { |column| column.name }
693:       end
