List supported languages in Info.plist

If the system's language setting isn't listed here, Pinta will just be launched with the default locale when running from the app bundle (from the terminal, the LANG environment variable may cause the expected locale to be used)

Fixes: #1976178

@@ -26,6 +26,7 @@ Thanks to the following contributors who worked on this release:
 - Added a "Reseed" button for the random noise used by several effects ("Add Noise" and "Frosted Glass").  Previously, the noise pattern changed every time the effect was computed (including when other parameters were changed).
