Stamina For Tweakers

Fixed

• Shield use code now checks a tag (staminafortweakers:shield) instead of checking for the minecraft:shield item. Some modded shields may work out of the box, others may need to be added to the tag with a data pack.
• No longer checking for item tags during Better Combat AttackStart events, since the event won't fire unless BC thinks the player is holding a weapon. Should fix weapon swing exhaustion for most modded weapons when BC is installed.
