.DS_Store files in data pack and resource pack folders are read by the game and cause error and warning messages to appear in the game output log.

How to reproduce:
Launch a Minecraft world with the attached data pack or resource pack installed (On a MacOS computer).
When in game, use the /reload command to reload data packs.
Or use the F3-T command to reload resource packs.
Check the game output log.

Expected Result:
These data and resource packs should cause no error messages in the game output window. The files themselves have no errors.

Observed Result:
Warning and error messages appear in the game output log, caused by .DS_Store files.
