EventLoggerForIM

This release updates dependencies and enhances logging functionality by including the server’s local and external IP addresses at startup while also refining teleport logging to exclude redundant messages when coordinates remain unchanged.

• Updated pom.xml dependencies and base Paper dependency to 1.21.5-R0.1-SNAPSHOT.
• Added local and external IP logging to server startup messages.
• Refined teleport logging in player handlers by including a teleport 'cause' and skipping logs for unchanged coordinates.

This release should support 1.21.5 when it's officially available. I don't think there's anything new or different that would impact functionality, but if it does I'll update it and release a new version.
