* Document GetTattooShopDlcItemData

Researched the struct values from shop_tattoo.meta and changed few stuff.

* Update GetTattooShopDlcItemData.md

Made the structure properties and character types into a table + added a LUA example.

* Change the CharacterType param description

* change tables to enums and structs

* add suggested changes

* tweak: add language tags to structs
