Collect translation files into a single directory,

where they can be accessed by the flutter i18n library.

Translations provided from crowdin are located in subdirectories,
|

but we need the .arb files to appear in this top level directory
|
|
to be accessed by the app.
|
|
|

So, simply copy them here!
