status_with_schema doesn't work with multiple migration_paths

[andrewjstrominger]

I recently found that status_with_schema doesn't work when following the Engine directions to add another migration path.

This doesn't work:

Dir.foreach(File.join(Rails.root, migrations_paths))

Errno::ENOENT: No such file or directory @ dir_initialize - HIDDEN
<internal:dir>:98:in `open'
/Users/andy.strominger/.rvm/gems/ruby-3.2.2@rotom/gems/data_migrate-9.0.0/lib/data_migrate/tasks/data_migrate_tasks.rb:70:in `foreach'

I put up a PR to fix it: #291
The PR changes it to:

Array(migrations_paths).map do |path|
  Dir.children(path) if Dir.exist?(path)
end.flatten.compact.each do |file|

(Copy/paste from right below it).
