Image Emojis: Emojis in chat

• Added the DiscordSRV support:
  • When you send an emoji in the Minecraft chat, it will be correctly translated to the Discord emoji template.
  • When you send an emoji in Discord chat, it will be correctly displayed in the Minecraft chat.
  • It works only with emojis with the same name both on the Minecraft server and in the Discord server.

* This change doesn't require you to install DiscordSRV, it's optional.

• A minor adjustment for better compatibility with legacy chat formatters.
• Added configurable actions for cases when a player doesn't have enough permissions:

# What will happen if a player doesn't have the "imageemojis.use" permission?:
# ERASE_EMOJIS - Erase all emojis from payload and proceed.
# CANCEL_EVENT - Cancel the event completely (e.g., prevent the message from being sent).
noPermAction:
  inChat: "ERASE_EMOJIS"
  inAnvils: "ERASE_EMOJIS"
  onSigns: "ERASE_EMOJIS"
  inCommands: "ERASE_EMOJIS"

# Whether the player will see the "Not enough permissions" message.
# Will be shown only for events with the "CANCEL_EVENT" action selected.
noPermMessage: false

• Removed support for .jpg and .jpeg due to their incompatibility.

• Introduced the imageemojis.use (true by default) permission to control who is allowed to use emojis.
• Fixed incompatibility issue with legacy Spigot chat formatters (such as LPC).

• Minor improvements in handling enum types from the configuration.
• Added the ability to customize the format of emoji templates in the configuration:

# Emoji template format (e.g., you may replace semicolons or remove them completely)
templateFormat: ":<emoji>:"
