Image Emojis: Emojis in chat

• 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
