Fix SpellArchive variant lookup

This PR fixes SpellArchiveModelRetexture to use the canonical blockstate root for baked model lookup.

spell_archive is the only blockstate root for this block. The books value is a blockstate property, while spell_archive_1 through spell_archive_14 are model files under models/block/.

Before this change, the bake code used spell_archive_1, spell_archive_2, etc. as the ModelResourceLocation root, which caused invalid lookups:

errors like: spell_archive_1#books=... lookups are gone and the archive variants render correctly in game.
