ci: add option for the ci to check locales

[Totto16]

Pull Request Template

Description

add support for a "dry-run" to "generateLocale.ts" , so that locales get checked in the CI

This helps in the case of locale updates, as the CI catches such things as in #305

This was done in a quick fashion and can certainly be improved, I didn't use a cli parser, since this just adds one simple optional option.

Any suggestions for improvements or arguments against this are welcome. ❤️
