Malformed patchouli data in 1.18

[loldev69]

In version 1.18 of this mod, the extra_recipe_mappings entry in the dimensionalcell.json file contains an array instead of a JSON object, causing patchouli to log an error and skip this entry (the rest of the book still works).

This issue was already fixed in 1.19 via this commit, backporting to 1.18 should work as tested via datapack replacement.
