Fix error that undefined method `schema_format' in AR 7.1

[matsubara0507]

Error occurred when invoke ar:migrate:redo in AR 7.1:

% bundle exec rake ar:migrate:redo MIGRATION_VERSION=1234
...
rake aborted!
NoMethodError: undefined method `schema_format' for ActiveRecord::Base:Class (NoMethodError)
/path/to/vendor/gems/ruby/3.2.0/gems/activerecord-7.1.5.1/lib/active_record/dynamic_matchers.rb:22:in `method_missing'

/path/to/vendor/gems/ruby/3.2.0/gems/rake-13.2.1/exe/rake:27:in `<top (required)>'
...

So I fixed it the same way as #2275

It might be worth considering adding a method schema_format_ruby?:

def schema_format_ruby?
  schema_format = if less_than_active_record_7_0?
      ActiveRecord::Base.schema_format
  else
    ActiveRecord.schema_format
  end
  schema_format == :ruby
end

Then dump_schema would be:

def dump_schema
  Rake::Task["ar:schema:dump"].invoke if schema_format_ruby?
end

I Added schema_format_ruby?.
Thanks!

This should be fixed on version 0.16.0.pre4. Could you please check?
