Add prettier CommandTree formatting for help command and usage hint

[user622628252416]

As discussed in #39

Current limitations: Help for commands with more than one branch ends after that branch. Vanilla Minecraft does that, too, but also allows displaying help for a specific branch if that branch is specified in the help command, which this pr does not implement.

Hey, Just tested it, Good work!. But i would still like to not display mutliple same commands in new lines. Like here

Help could be replaced with for example:
help/h/?.
So its in one line

Done 👍

It now looks like this

h
2024-08-21T17:26:19.239Z INFO  [pumpkin::commands] Text { text: "gamemode - Change a player's gamemode. Usage: /gamemode <gamemode> [<target>]" }
2024-08-21T17:26:19.239Z INFO  [pumpkin::commands] Text { text: "help/h/? - Print a help message. Usage: /help [<command>]" }
2024-08-21T17:26:19.239Z INFO  [pumpkin::commands] Text { text: "pumpkin - Display information about Pumpkin. Usage: /pumpkin" }
2024-08-21T17:26:19.239Z INFO  [pumpkin::commands] Text { text: "stop - Stop the server. Usage: /stop" }
