Bring languages into the tree (#1625)

* translations: bring languages into tree

* Update translation phrases changed since 2021

* Update packaging script to include all translations

* Update languages.cfg

* Add Latin American Spanish translations

This is a copy of spanish for now.

* Ignore "en" when looking for translation folders

English is the default and doesn't use a subfolder.

* Only add each translation folder once

Korean "ko" is in there twice.

* Compare language coverage to english

All phrases are compared to the english baseline files and any differences
are reported. The differences are pushed to a Github Project as well for
an easier overview.

Thank you to @nosoop for sharing the Python SMC parser!

* Add link to README
