Add workflow for downloading localization strings (#4657)

This is for automating download of localization strings from our localization team.

The handover schedule is every Monday/Thursday, while the handback schedule is every Thursday/Monday.

There are exceptions for holidays. This workflow allows manual run, in case we need the strings out of regular cycle.
