Unsafe Vanilla Enchantment Levels Broken in v9?

[blockpixelz]

Describe the bug I want to allow unsafe Vanilla enchantment levels by combining 2 max level books. But when I change the max-level attribute in the vanilla enchantments yml file and reload the plugin or restart the server, the file reverts back to its default and doesn't save. This worked perfectly in v8.

To Reproduce Steps to reproduce the behavior:

1. Go into the vanilla enchantments yml file
2. Put on a "max-level" attribute to any enchantment, adding "max-level: 10" to sharpness for example.
3. Reload the plugin or restart the server
4. The file will now be reverted back to the default

Expected behavior When you combine two max level books in an Anvil, it should create one that's the next level.
