Display key folder and file structure is flattened

In Guidewire Studio, the configuration > config > Localizations folder, which contained the display.properties files, no longer contains subfolders for each locale. Instead, the locale is now included in the file name, and all files are located at the top level of the Localizations folder. For example, the file en_US/display.properties is now named display_en_US.properties.

The underlying directory and file structure in the file system also reflects these changes.
