Enchantment Level Language Patch

Changes way to swap between numeral and roman:

Now using langpatch.conf.enchantment.default.type and langpatch.conf.potion.default.type to determine which format is used.

• simplified, chinese, zh_normal -> Chinese numbers (lower case) e.g. 一二三

• traditional, zh_upper -> Chinese numbers (upper case) e.g. 壹貳叄

• numeral, number, numeric, arabic, default -> Arabic numerals e.g. 123

• roman -> Roman numerals e.g. I II III

enchlevel-langpatch:default and enchlevel-langpatch:roman hooks are functionally equal now.

Technical: registries will be frozen after LangPatchImpl::init, which requires sub-mods to register before it.

In Forge: register in mod constructor

In Fabric: replace client entrypoint with enchlevel-langpatch.init
