Update to Minecraft 1.20.4 plus a small fix

[TomyLobo]

Thanks again for your port to 1.20/1.20.1 and 1.20.2.
I actually found a little issue in your port to 1.20.2.
Tab completion of names only works within commands.
This PR fixes that issue and ports the mod to 1.20.4.

Known issues:

• Ctrl+Backspace/Del deletes the word, but doesn't refresh the display

I would recommend relocating this pull request to the upstream repository at https://github.com/DarkKronicle/AdvancedChatCore for visibility, because a PR on a fork is much more hidden than a PR on the main project.
(I would rehash the same point on the other PRs, but I don't believe that there's much point in it. Thank you for the port, either way!)
