Refactored the YardWatch.java file to check if the GriefPrevention plugin is enabled. If enabled, GriefPrevention Protection is registered. Additionally, a new class GriefPreventionProtection.java was added which checks if a location is protected, if a player can break/place a block, interact with a block or entity, or damage an entity based on GriefPrevention's claims. Moreover, added a new dependency for GriefPrevention in pom.xml.
