fix error response of /format-code

[danthe1st]

Currently, /format-code fails to send a reply in case the message ID is not a valid Discord message ID.

java.lang.IllegalStateException: This interaction has already been acknowledged or replied to. You can only reply or acknowledge an interaction once!

This is because the interaction is acknowledged before using event.deferReply().queue();.

Using event.getHook().sendMessageEmbeds() instead of event.replyEmbeds() fixes that as the former works with consecutive messages.
