Issues in 1.20.4

[LessThanBenji]

Hi, I'm aware this isn't updated to work with 1.20.4 yet (as of writing this, the project's main page states 1.20.2 is the latest supported Minecraft version), but I thought I'd just note down the specific issues running this on 1.20.4 causes for anyone experiencing the same issues.

(This is all on a Fabric server running Minecraft 1.20.4 using the Windows executable release of mcsleepingserverstarter on Windows 11)

The main issue is the reason displayed to the player upon being kicked when joining while the server is still starting up from sleep just shows up as the "Failed to decode: Not a map: null null" internal exception in #244 (which I notice has been closed despite not being fixed... was it closed as not planned or something?).

Another issue I've noticed is you can't put any formatting whatsoever in either the serverName or serverMOTD lines. Using either the § symbol or the full \u00A7 doesn't matter; either will cause one of two issues depending on the specific situation: a) mcsleepingserverstarter will crash immediately on start-up (this usually occurs if you've used any symbols that are going to require a "" prefixing them, eg. "!") or b) mcsleepingserverstarter will load successfully and function correctly, but the server's MOTD and/or name when viewed in the server list in-game (and I'm assuming online as well) will just be entirely blank.

There may be more issues, but from my brief couple of hours testing these seemed to be the two most noticeable.
