After uploading the world folder containing the datapacks to realm, the damage_type file in the datapacks folder was incorrectly deleted, causing datapacks to not work properly.

What I expected to happen was...:
After uploading the world folder to the realm, the damage_type file in the datapack will not be deleted and the datapack will function normally.

What actually happened was...:
After uploading the world folder to realm, the damage_type file in the datapack is deleted as useless and the datapack does not function properly.

Steps to Reproduce:
1. Upload world file with datapack containing customized damage_type to realm.
2. After entering the realm, I found that datapack was not functioning properly.
3. Downloading the world folder from realm and looking at the realms-upload.log file in it reveals that the damage_type file was deleted as useless.
