End Portal Timer

Added Hologram Display when a player tried to place the ender eye on the end portal frame. (thanks @SnowCutieOwO for the suggestion!) Make sure to have DecentHologram installed to use this feature.

Config update (copy and paste this to your config):

# Cooldown in seconds. You can adjust this value as needed.
hologramCooldown: 1

# The format of the message to send to players when they attempt to use the end portal and when the portal is accessible
messageFormat:
  - "&fEnd Dimension will be accessible on:"
  - "&6%endportaltimer_date% %endportaltimer_time% %endportaltimer_timezone%"

Updated the link of the timezone database. https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
