Add a message if you reinforce a note block or jukebox reminding you that they're custom blocks now

        event.player.sendMessage(
            Component.text()
                .content(
                    "(Snitches as you've seen on CivCraft and similar servers don't function as you're used to. " +
                        "Instead, you need to craft a Snitch, which can be found in the Custom Items tab of the Recipe Book.)")
                .color(NamedTextColor.AQUA)
                .decorate(TextDecoration.ITALIC))

Right now LeerTutorialGiver.kt has this message if you get the tutorial by placing a noteblock/jukebox, but you'll only get it the one time so you could miss it. Instead, you should get the message every time you reinforce a civcraft-style snitch
